You see how trying to have a reasonable conversation with him is like trying to discuss astronomy with a flat-earth believer? He imagines he has "files" of "evidence" on others based only on his anger, while completely ignoring what is plain to see right in front of him. I recommend just muting and ignoring him. in a way, his continued presence just proves our reputation system works, and our principle of freedom on this platform means we don't delete even the raving lunatics.
