Twitter says it has "suspended a number of accounts" following the abuse that Robin Williams' daughter suffered on the social media site following his death.
A statement reportedly from Twitter's vice president of trust and safety, reprinted in the Washington Post, said:
We will not tolerate abuse of this nature on Twitter. We have suspended a number of accounts related to this issue for violating our rules and we are in the process of evaluating how we can further improve our policies to better handle tragic situations like this one. This includes expanding our policies regarding self-harm and private information, and improving support for family members of deceased users.
