NEW YORK (AP) -- Twitter says it is looking at how it handles its business after word that Robin Williams' daughter has given up her social media accounts because of online bullies.
Zelda Williams says she's abandoning her Twitter, Tumblr and Instagram accounts "for a good long time, maybe forever" after getting abuse from some posters.
The grieving actress got disturbing images and verbal attacks after her dad committed suicide.
Twitter says it has suspended some accounts because users violated the site's rules -- and will reconsider policies to better support grieving families.
