I'm talking about a permaban here that affected a lot more people than just me (shared IP).
I must have the lamest list of reasons for getting a ban ever:
1) posting during /b/ invasion (while not being fom /b/)
2) posting full nudity with spoiler tags (i admit, it's stupid, but everyone was doing it)
3) posting two boobs under a spoiler tag (something that gets done all the time, I even put a NSFW warning)
4) permaban for a completely work-safe joke thread in /tg/. It was permanent because of my number of previous bans and came with a message "you have been banned 3 time already. just get off of 4chan.". That would have made sense if people didn't post porn in another thread there at the time I got the ban.
That's really fucking unfair.
