Twitter is making it easier for its users to avoid seeing posts or messages from online trolls and other harassers, by adding the ability to import and export block lists from the service. Users can export and share their block lists with others, as well as importing and activating other created lists, allowing for large groups of trolling accounts to be blocked by multiple users in a group in a short space of time.
The block list export and import options will be useful for members of some online groups, especially public figures, those involved in major feuds, and where some users harass others online based on their ideological views. The process is still fundamentally manual and does not include any automatic updating between users of the same block list, though it does still provide users with full management of their own list, unblocking individual accounts mistakenly blocked by the new list.
The block list sharing is the latest tool Twitter has introduced to try and combat online harassment. In December, it made the flagging of abusive tweets simpler, and introduced the blocked accounts page. In April, it updated its abusive content policy, as well as added internal tools that allowed employees to temporarily lock abusive accounts for specific periods of time, to act as a cool-off period.
