Who is @KT_So_It_Goes? He has called me a white nationalist and run a multi-year slander campaign. If you know, please tell me so I can figure out his motivation/malfunction.

Yes, I block him, because he uses his large following to slander people and sic mobs of anonymous, vile trolls on people.

And if you follow him, please consider that he is not a good-faith actor. You should unfollow him. Probably block him.
