I have a friend who helps to runs an anime con, and once in a while, he asks me to help out (usually as staff). 2019 (if i remember right), we passed a rule banning ahegao shit, since one, it was too sexual , (also, the place that hosts our con was getting a shit ton of complaints about people with risqué outfits and almost banned us), two, since a shit ton of the women (and men) in the pics are lolis and shota and they didn't really want pedo shit at the con since it was starting to get attention by the public. that year we had a shit ton of women (about 18-22) wearing them. they always yelled at us and told us that we were boomers/libtards. we also had one bootlegger that year trying to sell them downlow and almost got kicked out for it.
