The Twitter has announced three new changes to combat online harassment. It will not allow Twitter abusers to open new accounts. The Twitter has introduced an option called ‘safe search’ to remove tweets which contain sensitive content. It is also removing objectionable tweets from blogs and muted accounts. Abusive replies will be collapsed in a conversation. The Twitter has been constantly criticised for doing nothing against objectionable content. The three new changes will make a difference in the better functioning of Twitter.
