Happened to me once, too. Only time I ever got a site ban and it was for agreeing with a post about punching Nazis. The main post stayed up, while they systematically banned everyone who agreed with it for promoting violence. I spammed the appeals inbox until an actual person responded and unbanned me. But it was just another thing that had me looking for alternatives and then the API bullshit happened and Lemmy was brought up. Been here ever since.
