I don't really have any crazy stories that don't involve being ghosted or the other person ending the RP before it can even begin for some stupid/petty reason, but my worst (and, thankfully, only) RP story that I can remember is this one time where someone commented on every RP ad I would make just to harass/bully me. It started with a reply to one of my ads, saying the idea was cool, but not for them. I replied and asked them why they would reply to my ad instead of scrolling past if they're not interested, and they decided to use alt accounts to comment on every ad I would make to call me a loser and basically bully me into quitting roleplaying. I reported and blocked them and their alt accounts, but I was paranoid that they would come back and bully me again if I posted another ad, but I haven't heard from them in a couple years, so I think I'm safe from them
