Twitter has defended its handling of misinformation and abuse in the aftermath of this week’s shooting at YouTube’s headquarters. In a blog post titled “Serving the Public Conversation During Breaking Events,” trust and safety VP Del Harvey laid out how Twitter tried to provide “credible and authentic” information about the attack, even as some users spread hoaxes about the shooter’s identity.

Harvey writes that Twitter doesn’t have a system for verifying information accuracy, reiterating Twitter’s stance that it isn’t an “arbiter of truth.” However, it watches for deliberate misinformation that violates rules against harassment, hate speech, spam, or violent threats. Harvey says that after the shooting, Twitter “suspended hundreds of accounts for harassing others or purposely manipulating conversations about the event” and implemented automated systems to stop suspended users from making new accounts.
