That is true, but you only get those high upvotes by writing high-quality comments (which almost nobody does).

I have to mute 1/4 of the commenters and the other 1/4 barely write a sentence the other 1/4 is trying but failing and the other 1/4 write slightly above average comments.

Yeah, that is totally true. I haven't had much experience of being commented upon, but I do see a lot of spam comments "thank you! i like this" and super dry comments.

Indeed, super annoying.
