As long as the thread is clearly called out as NSFW, I have no issues with it. I do follow the regular Tapas guidelines (no porn, no penises and no vaginas, sorry) when judging those posts.
What I will remove without question is a NSFW post on a normal thread. It's rather rude to innocently scroll through a thread that morphed from "look at my adorable panda drawing" to "I did this great sketch of decapitated puppies, guts and all!".
With all those things I can't stress enough that flagging is the most powerful tool here. I'm the only active moderator right now and am unable to look at everything. You guys see something weird, just let me know.
Since I'm not a staff member (I'm just a member of the community like all of you), I won't see @ staff. That goes to Tapas employees only. Not sure if @ moderators works, I have never actually seen it - try it!
