Today, we’re announcing three changes: stopping the creation of new abusive accounts, bringing forward safer search results, and collapsing potentially abusive or low-quality Tweets.
In the days and weeks ahead, we will continue to roll out product changes – some changes will be visible and some less so – and will update you on progress every step of the way.
The only one that really affects your day to day Twitter usage seems to be the automatic collapsing of “potentially abusive” tweets. It’s not actually deleting or blocking the tweets rather just hiding them in their official client as demonstrated in this GIF.
