Something you can do is tell @TeamYouTube that you stand with the BlackTruth, and want ProfBlackHQ reinstated. Tell them you recognize YouTube is hostile (perhaps illegally so) to any views they don't personally agree with and censor users behind the false claim of "hate speech."
@TeamYouTube Professor Black Truth is one of the FEW content creators who's message is engaging. This punitive action is creepy and dystopic. The slimy tentacles of censorship have scrubbed all references of his channel. Reinstate him, else people will find an alternative.
