I do think the thread could benefit from either
a] Only putting NSFW art/fic in the fanworks thread we have, to avoid unpleasant surprises (and mod action against people in the thread; make sure to link to these instead of posting them directly in the thread! I'm pretty sure it's against the forum's rules to post stuff like that directly on the forum)
or
b] Making sure to clearly write why something is NSFW, rather than just saying "NSFW" and leaving it at that.
Sometimes I play/review games that are rated 18+ on my Tumblr, and I include specific warnings in the tags of those posts so that my followers can easily avoid content they might find upsetting or uncomfortable. For fics, putting the description of the fic would be much better than just putting a link to it and saying "NSFW," even if you don't say anything more than that; the fic you're linking to could be a super long fic with one quick near fade-to-black sex scene or a raunchy PWP, but without any sort of description there, there's absolutely no way of knowing what you're getting into before you click on it.
I think in theory this is a great idea but some things are bound to slip through. There are far too many variables for even a description posted to sufficiently warn someone with certain triggers.
I'm not saying we shouldn't add descriptions but I am saying that we should pick our battles before this thread turns bitter like so many others because there is just no way to respectfully enforce the rule.
And what I may consider harmless from behind action someone else may consider that to be Solas treating Lavellan like an animal and be offended.
I'm all for making it work for everyone, though. If I ever post fanfic in the future I will be sure to appropriately label it for any personal triggers. Its all we can really ask from anyone and hopefully that will be enough.
