This is indeed a recurrent subject and will never have an all members satisfying solution. I don't see what that other topic got locked and have unlocked it.
The easy part to answer is why straight porn got allowed: it was requested by members focusing on the male models in straight porn. Especially straight porn with older male models got a strong followship among members into older male (there seems to be a lack of older male gay porn). There have been put filter options in the Profile settings, so that "pussies" can almost be filtered out (except when wrong categorized, which is worth a report).
GayTorrent.ru doesn't aim to be a general movies (and porn) tracker. Therefore the non-porn requirements were always somewhat restrictive. The requirements were made lower by changing "Gay" themed into LGBTQ (Lesbian, Gay, Bisexual, Trans* and Questioning) themed and allowing with "recurrent subplot" (only) over the times.
When a torrent is reported for sharing content not fulfilling the "LGBTQ themed" or "voyeurism of the adult male physics" requirements the staff takes considerable efforts to review the shared content, often involving multiple members of the staff, reading reviews, questioning the uploader or even viewing the movie.
This would become even more difficult if sharing content stamped "gay interest", (gay/queer) "camp" or "gay cult", because how to verify and/or decide it is that or not …?
