I agree, most of the anti-fanfic stuff was aimed at the more extreme R-rated end of things - but there have been a lot of people flagged as posting unacceptable content for posting something that is entirely legal in their own country, but borderline illegal in the USA if given the worst possible interpretation, e.g, stories about the adult lives of fictional child characters. There have also been problems with e.g. the rape victim's group who were not allowed to mention it in their interests, and other examples of excessive zeal in the people who enforce these rules.
