British Labour MP Jess Phillips received 600 rape threats the night after launching a campaign to end sexist cyber-bullying.
The MP for Birmingham Yardley hit out at Twitter for allowing “mass bullying,” adding that she has received around 5,000 generally abusive tweets since beginning the campaign.
Phillips told foreign media that she would need to hire someone “full time” to block all the abusive messages she receives on social media.
The MP is among a group of leading female politicians, including former Labour leadership candidate Yvette Cooper, who launched Recl@im the internet – a campaign to stop hate speech and abuse online.
Ms Phillips revealed earlier this year she was sexually assaulted as a teenager and she has spearheaded campaigns to highlight sex abuse, domestic abuse and online bullying since being elected an MP in last year's General Election.
Her campaigning on Ms Phillips has been a regular target for Twitter trolls. The wave of abuse she received yesterday appears to have been launched after she replied to one person who told her: 'I wouldn't even rape you'.
She has previously been subjected to rape threats online after she laughed at Conservative Philip Davies when he called for a discussion in Parliament to coincide with International Men's Day last October.
Research by think tank Demos found that over 9,000 “aggressively misogynistic” tweets are sent each day worldwide.
