Oddly enough, none. Kind of like seeing the sheer variety the Internet had to offer (plus those folks have so much confidence it's almost admirable). And at least it's not gore-- I've seen accidently seen way too many dead bodies mindlessly unblurring pictures on Reddit or foolishly clicking troll links.

Probably going to change to block nsfw when my little ones are old enough to steal my phone and browse my account, though.
