I am not clear about flagging, I don't want to get myself tagged because I flag-ed someone 3rd submission of his weekend Rust project, or those COVID conspiracies/magic cures, I could offend some free-speech extremist if I have the opinion that the HN is not the correct place for that.
Yeah flagging is the most extreme, for things that really don’t have anything to do here. It’s rare that a flag-able story ends up on the front page, to be fair, but a COVID magical cure or a propaganda piece for the usual quacks would fit all the criteria to be flagged to oblivion.
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.
