The social network is doing more to follow up when someone has crossed the line, too. When you report someone, you'll get in-app notifications when Twitter receives a report and takes action against an offender. You won't have to check your email to see if the company has suspended that troll you reported the other day.

The changes should be available worldwide in the "coming days and weeks." The mute controls aren't Twitter's strongest weapon against abuse, since they don't actually stop trolls by themselves -- you just don't see their vitriol in your mentions. However, it might discourage harassment by making it clear that the targets won't have to put up with that hate, even from dedicated harassers who create new accounts as quickly as the old ones are knocked down. If nothing else, it shows that Twitter was telling the truth when it said it would pick up the pace on anti-abuse features.
