I enabled hiding my posts because I kept getting harrassed and even doxxed.

Last time I used Reddit, I posted in r/bitcoin and immediately got banned because they looked at my post history and saw that I'd posted in r/btc, which is apparently not the same thing and "at war" with the other place. There was probably some Reddit-specific history they knew that I didn't, but who cares, there's no reason to waste your time with people like that.
