1. Please do not post hentai in aba/abma/abmar
1. It is explicitly against the aba and abma charters.
2. Do not give isp's a reason to drop aba/abma. If I may quote from Marco van Loon (the originator of abma):: "It doesn't contain *erotic(a)* in the name, so allowing hentai material would make this a stealth erotica newsgroup." and thus a target for isp's wishing to "clean up" Usenet.
3. Other groups already exist that are more appropriate for hentai posts. Recently alt.binaries.multimedia.erotica.anime has been the "default" hentai ng.
