Twitter not protecting women from abuse, says Amnesty

Human rights group says trolls are winning as site has become toxic place for women

Twitter is failing to prevent online violence and abuse against women, creating a toxic environment for them, Amnesty International has claimed.

In a report published on Wednesday, the day that Twitter celebrates 12 years since the first tweet, Amnesty said the social network responded inconsistently when abuse was highlighted, even when it violated its own rules.
