I donโt think itโs about tagging guidelines, since Derpibooru also allows diaper fetish to stay as a safe tag.
Derpibooru has a lot more users, uploaders, taggers, reporters, etcโฆ
Pretty much the entirety of stuff here is diaper fetish. Iโm not kinkshaming, but surely it can warrant a little rating upgrade?
I really donโt want to sound confrontationalโฆ but have you reported any of this before?
Stuff slips by because staff also have their own filters for casual use and arenโt checking every tag and filter combo when looking through all images. Problems like these can often be resolved fairly easy and painlessly with just a report and a mod poking the uploader, rather than a rule change or finicky tag implication.
