@alyx Well it's been intensifying lately for me, I don't know if it's been ramping up or if I've just been noticing it more and more and losing what resistance to it I might have. I use gelbooru and my list of negative tags/antitags is a mile long and expands daily as people add new tags for new degrading and awful things. (Especially my actual ptsd trigger, r*pe. There are like new tags for that every other weekend it feels.)
And definitely yeah, browsing a site like that without antitags is mentally draining and demoralizing at best or triggering and panic attack causing at worst.
