They weren't all porn parodies, and even the admins/staff post/PM inappropriate things, all the time.
Everybody posts inappropriate things, all the time, and that rule is virtually non-existant, and never enforced.
Amith's personal attacks are also somehow not against the rules, even when it
IS a rule not to make personal attacks.
Go to your local fye shop, and see the 50,000 anime porn titles that they sell.
By the way, "typical" American anime magazines
DO cater to the perverts, and I have met several "typical" anime fans who
ARE perverts.
