Plot bunnies breed, they’re always breeding.
It may be legal issues. AFF is hosted in the US which has the first amendment, other countries aren’t so lucky. Even in the US, you’ve got busibodies sticking their noses into other people’s websites and try to censor via court/legal-threats when they see it (ie, why bother with parental oversight when you can try to Disney-fy the entire internet instead?). IIRC, AFF has had to fend off threats to its existence, a mod/admin with good memory could fill us in here.
