If you ignore the fact that it's a 'fanfiction' site...
Archive of Our Own has one of the most liberal posting rules of any of the sites.

Offensive Content Policy
"Unless it violates some other policy, we will not remove Content for offensiveness, no matter how awful, repugnant, or badly spelled we may personally find that Content to be."

The 'other policy' they reference comes down to literal CP, and ToS things you wouldn't care about.
