Facebook has said it will block "praise, support and representation of white nationalism and separatism" on Facebook and Instagram from next week. ... The social media giant also pledged to improve its ability to identify and block material from terrorist groups. ... Facebook users searching for offending terms will be directed to a charity which combats far-right extremism.
Call it a guess, but this won’t end well for FaceBook. Their centralized algorithms will likely be a clumsy response.
At least some of these white nationalists may migrate to the Steem blockchain, so be ready to flag them.
