A labeling system.

[KaneLives]

After reading for awhile, an idea occurred to me. Because of the incredibly wide selection of stories here, and the rule of no tag enforcement, that a super simple single tag system in the concept of what the movie ratings system, or what the PEGI system for games was supposed to be might work here. The idea is for a simple set of tags be made that every story could use to tell what broad category of idea/topic/content will be inside.
The first tag could be for stuff that would be for stories that are mundane/less problematic. The top tag for the stuff that even a lot of hard core kink lovers would tell the author to chill.
As with the movie rating example, the lower for stories that even teens would be good for on average. The next few for stuff dipping closer to more 'complex/touchy' topics or the like. An example would be Game of Thrones type stuff that gets pretty in depth of description of gore, rape, murder, etc, without actually getting to pure murder porn. The top would be for stuff even porn sites can add a simple 'are you sure you want to continue' level.
Not really sure how many layers would be best, but my brain is thinking 5 should be good. It doesn't need to be forced, but more a guide line so people could better filter out or for stories they actually want.
I know it would be a definite long term idea that would take a lot of tweaking and checking, but it could help the more 'casual' (it's QQ, so even that's a pretty lose term) reader doesn't just up and stumble into 'murder hobo harem protagonist with magic dick powers of ultimate sexual prowess' and freak because the tag was Pokémon, SI, and action, as the only tags (pulled these 3 only for pure example).
Either way, shooting the shot of either this can help, or spark an even better idea.
Edit for autocorrupt screwing me up.

and the rule of no tag enforcement

I think you have already identified the biggest reason against this idea.

Given that there is no tag enforcement, trying to pitch any system that would involve any level of tag enforcement is a hard ask.

As Kraken said, that would require tag enforcement because people who aren't properly tagging their stories now aren't going to start using that specific set of tags.

Also, trying to create tiers of fetishes just sounds like it would lead to countless arguments because obviously the stuff I am into isn't as bad as the stuff you are into but I am not.
