I find the upvote/downvote model of ranking threads and comments quite good in principle. I do enjoy some subreddits, none sports-related, which are well moderated with balanced viewpoints in the comments.
Problem is when the "community" & mods are highly biased, opinionated, and sometimes on the young/ignorant side. It is worse on Instagram.
storytime:
I've been blocked/banned on several platforms for posting facts which disturb the hivemind (or echo chamber). Best was probably being banned for "misinformation" from r/news for stating the Canadian Trucker Convoy was very large in response to a biased and wrong News article downplaying it's size and significance early on. I was later un-banned without comment, but unfollowed anyways.
