Twitter working on preventing suspended abusive users from opening new accounts

Twitter announced that they are currently working on identifying hateful and abusive users who have been suspended and preventing them from opening new accounts. The announcement was made, in a blog post by Twitter's engineering chief, Ed Ho:

'Twitter is working on identifying users that have been permanently suspended and prevent them from creating new accounts. This new measure specifically targets "accounts that are created only to abuse and harass others,"  a problem that has long plagued the platform.  

The new safe search function prevents tweets that are abusive or from blocked and muted accounts from appearing in users' search results. Those tweets can still be found if people want to see them, but they "won't clutter search results any longer,". 

Twitter's decision to hide or collapse abusive content, rather than delete or ban it, is in keeping with its long standing position as a defender of free speech and "people being able to see all sides of any topic,"
