You'll have to convince creators of that. They decide what tags there are and how they're described. For example, yaoi and yuri exist, but not "hentai" for instance. And that reflects community preferences.
How odd,is there a way i could go about that? perhaps a forum thread with enough people opting in for it?
That sounds like a plan. Plenty of people read the community forum. At the very least it could be an interesting discussion.
