Twitter 's latest attempt to tackle the site 's problem with trolls is a 'Quality Filter ' . The tool works in a similar way to its 'tailored notifications ' and involves scanning tweets for abusive or offensive words , threats or signs of harassment . It will automatically remove these tweets from a user 's notification timeline and repeat offenders may be suspended from the site . Twitter 's 'Quality Filter ' will scan tweets for abusive or offensive words and threats . It will automatically remove these tweets from a user 's notification timeline and repeat offenders may be suspended from the site . It was spotted by Twitter user Anil Dash ( pictured ) and is only currently available to verified users . The tool was first spotted by Twitter user Anil Dash who wrote : 'Well , that 's an interesting and welcome addition , Twitter ! ( Was prompted about this on opening the app . ) ' Mr Dash is a verified Twitter user , meaning he has a blue tick on his account . These blue ticks are to confirm that the accounts of high-profile , influential people and celebrities are real and not parodies , for example . A Twitter spokesman said the feature is only currently available for these verified users and did not reveal if it will be rolled out further . It is likely due to the fact such celebrities fall victim to more abuse and harassment than regular users , but Twitter did not confirm this . From Mr Dash 's tweet it appears the filter is opt-in . Last week the site took aim at the rising levels of revenge porn and stolen nude photos posted to the social network . Its new rules ( pictured ) say that users must not 'post intimate photos or videos that were taken or distributed without the subject 's consent ' . The site said it will verify complaints and suspended abusive users . Reports recently claimed Twitter will start banning trolls and abusive users by tracking email addresses and phone numbers . When people sign up by email they are also given the option to add a phone number ( pictured ) . In the future , Twitter may ban accounts accused of abuse until they provide this number . Twitter already lets people block , report or mute people who are sending them abusive messages .

Its rules now say that users must not 'post intimate photos or videos that were taken or distributed without the subject 's consent ' . Twitter said an affected user can report a post if they believe it contains photos or videos posted without their consent . Stories of abuse , threats and internet trolls have become commonplace on Twitter in recent years . Robin Williams ' daughter , Zelda Williams , left the social platform last year after being sent disturbing images in the wake of her father 's suicide . Feminist critic Anita Sarkeesian was threatened with rape , sexual violence and death by Twitter trolls during the 'Gamergate ' saga after she criticised the way women are portrayed in video games . In the UK , journalist Caroline Criado-Perez also received rape threats after she voiced her support for the campaign to introduce Jane Austen as the new face of the £10 note . Twitter users Isabella Sorley and John Nimmo admitted sending the messages to Ms Criado-Perez and both were jailed last year . Under copyright laws the video or photos technically belong to the person who took it and who can , in theory , distribute it as they see fit but Twitter 's rules additionally considers the people in the footage . It will ask the person reporting the abuse to verify they are the person in the post and that it was posted without their permission . Twitter said 'agents will then act on content posted in violation of the policy ' , including removing the post or suspending the accounts of repeat offenders . The changes follow reports Twitter would start banning users who violate its rules by tracking email addresses and phone numbers . This means that if an offender attempts to sign up for other accounts using these details Twitter will be able to intervene . Last month an internal memo sent by Twitter 's chief executive Dick Costolo revealed the 51-year-old thinks his site 'sucks at dealing with abuse and trolls ' . In the memo , Mr Costolo said he is embarrassed by the way the company handles abuse and that it must take stronger action in the future . Mr Costolo 's comments were posted on an internal forum among Twitter employees , after one employee raised the question of what more could be done to tackle online abuse . In December , a blog post titled 'Building a safer Twitter ' revealed Twitter is working on ways to make it easier to block and report abuse . The site has since improved the reporting process to make it more mobile-friendly , and it now requires less initial information . It has also improved the ways in which abuse can be reported to law enforcement .
Twitter is currently using the feature on accounts of verified users only . It searches for abusive and offensive comments , threats and harassment . It will then remove all these tweets from a user 's profile timeline . Feature is the latest tool being used to rid websites of bullying and abuse . It recently revealed new ways to detect and report abuse to the user .
