Other comments (~~can't find them now as the issue got full of useless comments~~ e.g. https://github.com/stylus/stylus/issues/2938#issuecomment-31...) also noted that the GHSA bot have nuked a lot of other npm packages since days or weeks in the same fashion, so it could also be an AI scanner going full full nuclear.
Agree it would be nice if people would stop posting "help! how can I fix this?" and "I fixed it by doing X", they were valid comments at the beginning, but now more than half of the comments are just these two
