TV presenter Lizzie Cundy has told BBC Breakfast she feels that Twitter should be monitored, after enduring what she described as "very abusive tweets about my family".
The comments came after the Manchester City player Micah Richards reportedly shut down his account after allegations of abuse.
Gary Lineker also recently announced he was going to leave Twitter for similar reasons, although he has apparently since changed his mind.
BBC Breakfast also spoke to senior lecturer in computing at Goldsmiths University of London, Dr Chris Brauer.
