Twitter is trying to stop the creation of new abusive accounts, bring forward safer search results, and collapse potentially abusive or low-quality Tweets.

The changes, announced today, are part of Twitter's efforts to make abusive tweeters less effective.

Twitter is taking steps to identify people who have been permanently suspended and stop them from creating new accounts.

The company is also working on 'safe search' which removes Tweets that contain potentially sensitive content and Tweets from blocked and muted accounts from search results. While this type of content will be discoverable if you want to find it, it won't clutter search results any longer.

Twitter's team has also been working on identifying and collapsing potentially abusive and low-quality replies so the most relevant conversations are brought forward. These Tweet replies will still be accessible to those who seek them out. You can expect to see this change rolling out in the coming weeks.

The updates come after years of criticism that the company hasn't done enough to combat abuse and harassment. It's part of a new push under Chief Executive Officer Jack Dorsey to clean up the social media service.
