i made a script
https://rentry.org/on6tfm7e
first i grokked a script to query all danbooru artists with at least 150 entries
then i grokked a userscript to put N of them in at random into the clipboard, replacing underscores and escaping parens
you can set N, record a keyboard shortcut, and move the box around. default @match is novelai image and localhost:8188

for example
