I think the best way to fight this AI shit is just to support actual creators. The cat's out of the bag with AI; our data's going to be taken and used without our consent whether we like it or not, so maybe we should put efforts into holding up those who create their own stuff. Comment/interact on people's writings and art. Make it worth them posting; make it clear that what the people are interested in isn't generated stuff, but things that people have actually done themselves. It's a drop in the ocean, but showing creators that it's them that deserve the support at least serves to cut off a tiny bit of oxygen to these AI hogs - and make a difference to creatives who are trying against hope to share with a community.
Reblog and put your rare pair in the tags/comments! I want to see the depths people will go to create, for the most random two characters in the most obscure media.
