as a person that came from the 3rd world country and new in fediverse environment, i genuinely would like to know about this.
edit: thanks for the replies! sorry, i literally don’t know the reason since i’m not a western lol. twitter/x is too biased especially when musk openly supports trump so i came here and seeing fediverse is mostly are harris or biden (when he’s still up for the candidate) supporters. don’t know about reddit tho, i only use reddit as a forum for linux and programming stuff.
I don’t think there’s any less karma farming on here. People still look at their up and downvotes, and I don’t think there was a legitimate industry for selling high karma accounts on Reddit. Not one that would make a difference at scale anyways.
The problem with Mastodon and Twitter is structural, it’s based around following people, not topics. It is inherently problematic because a) personalities and status get elevated over the logic of the argument, b) following people instead of topics inherently feeds people’s egos in a problematic way, and c) a given person can use their followers problematically (brigading, etc). On Reddit / Lemmy by following decentralized topics it eliminates or reduces most of these effects, though the mods controlling each subreddit can exercise some of the same influence.
You can turn that off in the UI. I did that and it mostly makes the place more tolerable, though I do find myself peeking sometimes.
