Christie, who was also penalised in the 500m final on Thursday, deleted her Twitter account the next day.
"I have had a few people threatening me, cyber bullying basically," Christie told BBC Two.
Christie 'gobsmacked' by judges' ruling
After consulting with Team GB officials, it was decided her account should be shut down to allow her to focus on competing.
"I have had to deal with abuse on the internet as well," she said. "So, I have found it hard."
Christie, who will race in her favoured 1000m event on Tuesday, looked more relaxed before putting in a final burst which allowed her to edge Italy's Arianna Fontana in a photo-finish before she was penalised and placed in last position.
Within minutes, it emerged that the Scot had been sanctioned for an infringement at the finish line.
