Oh well, for me smut definitely was an issue, seeing as I was in HP. I mean after awhile their was pornish_pixies. Which I can never remember reading fic in. You know why? Because I has parents. Parents who weren't afraid to take away internet access at the drop of the dime. Hell I read some tame(PG13 or R) crossgen fic where Harry was like 30, and got an earful of how and why I should never read it again, and that pedophilia is wrong. Trust me, that will be enough to scare anyone away from reading it(No seriously, I never got the "sex talk"; I got "Pedophilia is wrong--even in fiction"). Or at least at the time their was no TOR or I wasn't smart enought to subvert it in other crafty ways. However I always found it curios that I could have sex and get married(in my state) and they would turn a blind eye to drinking and smoking, however I was forbidden from reading fic about sex. Funny, right?

Anyway it is an obvious legal issue or fanfiction.net would have Nc17 fics still.
