There was one on r/UnixPorn, who was probably the reason why r/BetterUnixPorn was a thing. Kept removing my posts for literally no reason.

Don’t remember his name, but he spent a lot of time on some fetch sub (as in neofetch, pfetch, fastfetch, etc.)

I also once got banned from r/Socialism for saying China wasn’t communist. Whole place was full of tankies, and not just because of that incident.
