I just realized that lemmy doesn’t have karma like reddit. I’ve never paid much attention to karma. But even so it does seem to play an important role in moderation on reddit.
For instance, many subs put a karma restriction on who can post which helps decrease trolls.
And while it’s true that karma gives an incentive for people to seek karma I think it’s overall regulatory principle might be worth considering as a trade off.
Lemmy stores vote count for all posts/comments that it knows about. In case another platform doesnt support votes, the count might not be completely accurate. But anyway the count wont be accurate for remote users, because most likely we dont have all their posts/comments federated to the local instance.
