Is it ethical to block adverts online?

Blinking, beeping, auto-playing. Popping up, over, under. Tracking, intruding, unsettling. If the internet was a pretty face, advertising would be its wart.

Thankfully, if getting "a great six pack in weeks!" isn't your thing, you can simply flick a switch and use an adblocker - software that banishes the sight and hushes the din of irritating advertising all over the web.

The appeal is obvious, and millions have done it, but should you?

According to one count, 84% of the top 100 websites in the world rely on advertising to generate revenue, utilising the now long-established trade-off: use our website for free, but you need to look at some ads while you do it.

One site fights back...

The above image was displayed to visitors to online dating site OkCupid who had an adblocking program switched on.

On traditional mediums such as TV and radio, advertising has over time developed into a form of entertainment itself - just ask the millions who tune in to the Superbowl without any interest in football.

But online, evidence suggests we're far less forgiving. Adblock Plus, the most popular adblocking program on the market, has been downloaded 250 million times, and has around 60 million active users.

"I guess everyone agrees that online ads are just plain annoying," says Till Faida, co-founder of Eyeo, the firm that owns and maintains Adblock Plus.

"They don't work for most people, and most consumers have turned their back on them."

Mainstream adoption

What's more, as firms scramble to monetise however they can, it's arguably getting worse.

"Advertising has become even more aggressive," says Sean Blanchfield, chief executive of Pagefair, a firm that monitors how often advertising is blocked on websites.

"Most people are installing adblocks because of video advertising. That's where the mainstream adoption is coming from."

Adblock Plus sees its "mission" as being to encourage advertisers, and the websites that carry their material, to rethink how those ads work - minimising discomfort for internet users.

"Right now we block all video ads," says Ben Williams, Adblock Plus's director of operations. "It isn't inconceivable that in the future there will be a better format, but don't see that coming right now, personally."

Mr Faida adds: "We want to move away from the same old blinking banners, and encourage the industry to develop better advertising formats that actually work with the consumers instead of trying to force something upon them."

Yet an increasing number of people are questioning whether Adblock Plus's software is unfairly using its powerful position not just to encourage better ads, but also to build a quite considerable revenue stream of its own.

'Like the mafia'

It's no spoiler to share that most publishers or advertisers have little time for Adblock Plus - and recently that annoyance has stepped up a notch.

Descriptions like "extortion", "protection racket" and "like the mafia" are all terms being voiced to describe the operation, says Mr Blanchfield.

"I can definitely confirm that that's what most publishers call it," he tells the BBC. "And I can see it from their point of view."

There could potentially be an issue of a conflict of interest”

The row centres around a more recent addition to Adblock Plus's business, first trialled in 2011 but now gathering pace now it is out of its beta phase.

Where initially Adblock Plus would block all advertising, it now operates using a whitelist - a collection of, so far, around 150 sites and services whose ads are allowed through the filter.

To get on this whitelist, the advertising has to meet several fairly strict criteria: no animations, don't get in the way of reading text, and don't take up more than a third of a page's width, plus various other things.

Sensible parameters on the face of it, but here's the bone of contention: for "big" companies that want to be on the whitelist, Adblock Plus demands they pay a fee.

"Large companies that significantly increase their profits," explains Mr Faida, "In return support us to make the initiative sustainable."

If that fee isn't paid, advertising is blocked, even if it fits the "acceptable" criteria.

Pay up, in other words, or Adblock Plus will knock-out some of your revenue.

'Stirring up controversy'

Such descriptions of Adblock Plus are unfair, argues Mr Williams.

"To describe it as extortion is absolutely imprecise and wrong," he says.

"I think that people call it that all the time in the hopes of stirring up a bit of controversy here and there.

'Acceptable ads'

The principles of "acceptable" advertising, as defined by Adblock Plus and its volunteer community:

  1. Acceptable Ads are not annoying.
  2. Acceptable Ads do not disrupt or distort page content.
  3. Acceptable Ads are transparent with us about being an ad.
  4. Acceptable Ads are effective without shouting at us.
  5. Acceptable Ads are appropriate to the site or tweet that we are on.

But Mr Faida says he can understand why some people may be concerned at that set-up.

"There could potentially be an issue of a conflict of interest," he concedes. "We're trying to counter that with maximum transparency."

But both men argue that far from working against advertisers, they are instead playing the role of the much needed intermediary, working with advertisers in a way that keeps internet users happy.

Around 10% of the companies on the whitelist pay for the privilege, Mr Williams says, and he lists Google, Amazon, Yahoo and Reddit as some of the company's "strategic partners".

They would not not be drawn on how much they charge, nor do they give up any details on which companies had refused to play ball.

"There are of course cases where people are looking at it from a simplistic point of view," Mr Faida says of those firms distancing themselves.


The Internet Advertising Bureau (IAB), a UK-based trade association for online and mobile advertisers, released a report earlier this year that hypothesised what it thought an advertising-free internet might look like.

The report argued that if some of the web's most popular services - excluding shopping - did not carry advertising, users would each need to pay around £44-a-month, on top of existing fees, to make up the revenue needed to keep those sites alive.

While the trade association has an obvious motivation behind stressing the importance of advertising, the report does at least highlight how integral that revenue stream is.

"As a trade body we support innovation in advertising technology," says Nick Stringer, director of operations at the IAB.

"But we don't support the blocking of ads per se, because it denies publishers the revenues they need."

Although often descending into a bitter war of words, both sides of the adblocking debate at least agree on one core issue.

"The advertising industry just wants advertising to be relevant," says Mr Stringer. "The more relevant it is to the consumer the more attractive it is to the advertiser, and it's more valuable to the web publisher."

But targeted advertising requires sophisticated techniques to track users and their browsing habits - a highly-contentious issue, to put it mildly.

    Yes, it's entirely ethical: unlike TV and radio advertising, we pay for the bandwidth. It costs us to receive an ad, so it's right that it's our choice.

    This is the best that can be come up with by advertisers who know that flash advertising of one or two frames in a film is the best way to suggest to people that is what they want. An experiment was performed years ago that proved so successful this type of advertising was banned.

    You don't have to visit websites with video advertising that drains your bandwidth. Nor do you have to visit the websites that have intrusive advertising. There seems to be a sense of entitlement amongst people. Brand awareness and ingraining a product into your subconscious is quite effective, so adverts can and do work.

    I agree that there should be more regulation on advert targets and content.

    Blocking ads is at least as ethical as collecting data on users to target them with ads.

    Perhaps the people made homeless by these floods would be disadvantaged by blocking ads for insurance and refurbishment, be a nice little earner for those industries and government would be able to announce an increased growth in the economy.
    Perhaps Rt Hon Lord Whoever could ask their spouse to set up a charity to supply "discounted" laptops to those affected.

    The question should also be asked for those viewing on mobile devices with only a low amount of bandwidth why aren't the advertisers being asked to pay for the recipients bandwidth? 500MB a month and 50MB of adverts is 10% of the cost.

    It is exactly morally equivalent to using this website without paying the TV Licence.


    I use this website without paying the TV license since I don't live in jolly old England. What is it that I am stealing?

    I have an android phone and many apps, if an app is free with advertising or paid-for without, I would always go for the paid-for version.
    If a website had a choice of subscribing to remove adverts, I would do so.
    It is for that very reason that I refuse to use facebook. If it was possible to subscribe and not have them track your every move and sell your data to all and sundry; I would sign up.

    What about the ethics not involved in search engines that has helped drive the "how to get ahead in advertising" brigade...

    It's as if they should be charged with virtual soliciting, then they could go to virtual jail and if they pass virtual go should not claim £200 virtual or not.

    Advertisements_online - are regulated in the United Kingdom (UK) -
    by the Advertising Standards Authority (ASA). These state that Internet_Sites need to conform to standards that are linked to legislation relating to how businesses present & sell products by - transaction. Currently technology & online DNS servers are regulated with ISPs which do not have direct regulation & this should change.

    I don't have any ethical difficulty with blocking ads. Perhaps you may be shooting yourself in the foot by blocking ads as, if the content is paid for via advertising and the ads are removed due to ad blockers then different funding will be needed that you may have to pay for.

    Is it ethical for a site to guilt people into paying because they choose not to see ads that have already been paid for?

    Well from a Geek point of view, "my house my rules" so anything inside my web browser belongs to me to do with as I wish.

    A better question would be..

    I don't think people realise that the adverts are there to make the site owner money - regardless of how much the hosting or maintenance costs. I pay £5 a month for UK hosting (not a shared server in the middle of nowhereland) & that has enough for 95% of requirements for a website of heavy traffic. If you cannot afford to suffer hosting costs, then you don't deserve a site.

    I Hate all the rubbish advertising on the net. Block away please!!! I don't recall ever being tempted to buy a product or use a service etc as a result of them. Quite the contrary, in fact. All they do is annoy the hell out of me & get in the way of accessing the content I'm after. Those that pop-up, take-over, or erupt simply as the cursor crosses them should be banned.

    Database, what site doesn't use one? Most web hosts integrate PHP/MySQL into their packages for that very reason.

    60m page views a year isn't really that much. Some get that in a month.

    Most decent web hosts are more than able to provide that bandwidth and the dedicated servers to host it.

    But, whatever...
