Half of the sexist harassment women face on Twitter comes from other women, according to a new study released by British think-tank Demos on Thursday.

Demos' research revealed that both men and women share the same portion for conducting misogynistic abuse on Twitter as they used words "slut" and "whore," as indicators of gender-based abuse online.

The think-tank monitored British Twitter users over a three-week period and found that 6,500 unique users were targeted by 10,000 "explicitly aggressive and misogynistic" tweets in the UK. When the research was broadened to internatioanal level, researchers found over 200,000 tweets using the same terms, which were sent to 80,000 people in the same period.

Meanwhile, a previous research conducted by Demos showed that women are more likely to be subjected to aggressive and abusive tweets than men online.

The research was done as as five UK MPs; Yvette Cooper, Maria Miller, Stella Creasy, Jo Swinson and Jess Phillips launch a campaign "Reclaim the Internet" which calls for different institutions and social-media platforms to work together and tackle online sexism.
