I feel like many have not been following the rules and many have been posting straight content without using the proper tags which violates the rules. I've seen a torrent I have reported from way back on free leeches, and it still hasn't been moved into the straight category. Either do moderation or just ban straight contents altogether like before, it's not like there's a shortage of where people can find straight torrents/straight porn anyway, there's probably like 99 other sites (who btw doesn't allow gay content)

My understanding is:

Categories are not fixed or assigned by moderators but are more like tags.  The original uploader does assign the categories initially but they could change over time.  Members assign categories by voting for categories on the torrent pages for torrents they've downloaded  to earn a seedbonus point.  The category with the most votes is the primary category and then they follow in order of the number of votes received.

Some members may be assigning a straight category if the actors are straight, for instance OnlyFans or on videos from one of the studios specializing in straight guys getting blowjobs.  Or maybe they are just hitting the wrong button by mistake.
