I think the closest I've ever come to being censored was when I brought up a comic creators blog on another forum, highlighting one of his posts that I agreed with, and then a troll jumped on talking shit about that creator, calling him a hack and shit like that. Next day, I went to check the status of that thread and couldn't find it anywhere. I figure it got deleted, which was for the best, because it was a lightning rod to people who *were* dicks.
Other than that, DAP hid some boobies behind a spoiler tag in my early days. Thassabout it.
I generally censor myself before anyone else can.
