I heard they had naked pics of you mum up but they offended everyone so much that post was so bad they lit the server on fire.

Not much really ... but everything in s/WTF is automatically NSFW, most of which isn't.

same , I just found it a couple weeks ago apparently theirs mention to it in the welcome letter that I never received.

Almost nothing. As said, wtf. I don't remember anything else, but my nsfw was enabled since ever, so I'm not sure. Well, there's no porn, no loli and no gore, so no reason to keep it off.

Mostly just songs with dirty words.

I just found that I had NSFW disabled today. No idea.

Lol damn man. Tons!
