Tag use in general seems to somewhat arbitrary, or at least there seem to be at least a couple of different philosophies about how to apply tags. That likely occurs because there isn't any generalized guidance on how to tag things, or even on what some of the tags mean. The only guidance I can find is on tags is associated with creating torrents, and it just says that there has to be at least one tag (category) and that there may up to four more.
To illustrate this consider the following X generally described torrent descriptions and the tags that are on them. These are all real examples, meaning that I can find torrents that fit these general descriptions with the tags indicated, and yes, that includes all the tag variants. I'm leaving out anything where there is a substantive misapplication of the tags (tagging something bareback when it's not.)
- A torrent for a scene with two guys. They make out, the suck each other a little, they fuck bareback. This torrent could show up with the following tag sets. The first one listed is the "primary" tag:
Bareback, Anal, Oral Sex, Hunks
Anal, Oral Sex, Bareback, Jocks
What gets me here is the double tagging Bareback and Anal. In terms of strictly gay sex, doesn't Bareback necessarily imply Anal sex without a condom? The second thing is the inclusion of the Oral Sex tag. A pretty large number of gay sex torrents have at least some oral sex in them, if they all got tagged as such it would pretty much dilute what I see as the purpose of the Oral Sex tag which is to indicate torrents where the sexual content is primarily or exclusively oral sex.
- Now consider a scene where the guys don't fuck. The action is predominantly oral. This scene could have the following tag sets:
Hunks, Oral Sex
The last two don't make any sense to me as the scene doesn't show up when someone is searching for things tagged Oral Sex.
I could go on at length with examples but those show really the problems. I can totally understand the tag system is supposed to be user defined and holistic, but it strikes me that in the absence of any guidance (or the ability to apply boolean logic to tag searches) the usefulness of the current system is somewhat limited.
