San Francisco, Sep 25 : Micro-blogging site Twitter is working to limit the toxic replies users can get on its website by offering tools that allow them to be more proactive in preventing them from going through. In the future, those tools could include a feature that lets you filter potentially offensive replies and another that lets you limit potentially unwelcome accounts from replying, Engadget reported on Saturday. Twitter Senior Product Designer Paula Barcante has released a sneak peek of the features, which are merely concepts at the moment, to seek input from users. Barcante said Twitter will ask you if you'd like to switch on those controls if it detects potentially harmful replies to your tweets. If your reply filter is on, Twitter won't show you or anyone else, except the user who wrote the response, the harmful tweets it detects. If you decide to limit unwelcome accounts, users who've recently shown patterns of breaking rules won't be able to reply to your tweets at all. Since the process would be automated, Barcante admits that it may not be accurate all the time and may end up filtering out even respective, non-problematic responses. That's why the company is also exploring the possibility of giving you the option to review filtered tweets and limited accounts, the report said. /IANS
