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.
It sort of had. Boost for Lemmy used to calculate and list it untill recently. Not only for yourself, but for others as well. And deleting comments didn’t regain/lose any karma. It stopped doing that though.
