Just ignore/downvote/flag and move on, though. Nobody is forcing anyone else to read anything, and it’s normal that some people here are interested in things in which I’m not. None of us is the arbiter of what should or should not be on HN. Not us mere posters, anyway.
I don’t flag random projects, just ignore them (I know some people here like them, it’s not my thing but it is harmless). I downvote obnoxious comments about how something needs to be rewritten in rust in unrelated threads, though.
this is a case where i would flag the post rather than spend hours flagging comments, that would result in jail time if said IRL.
