I don’t think you can count the sites that just mirror Reddit comments.
Searching on lemmy.ml shows the top being several [email protected] megathreads with comments in the thousands, then that [email protected] post you highlighted, more [email protected] threads, then a [email protected] megathread about Hexbear’s federation. I guess we can see who comments the most.
I liked this [email protected] post Your username is the prompt, what did you get? which has 1618 comments.
Hang on, if you’re using CrowdStrike but not getting the updates, then why are you using it at all?
