I just grabbed the CSV files from the noob-wiki on huggingface and deleted the quotes and what not to make big ass text files for all of the artists and characters for Danbooru and e621.

All of them might not work but I was looking something like this and thought someone else might want it too. I notice some of the artists work better if you add more weight to them.
Just like the CSV files, which you can download in the link above if you want to see it, the text files are ordered from most uses to least. So the lower you go in the file the least likely to get the outcome you want to none at all. Have fun.
