There is already a total count of up- and downvotes, but please never add karma to Lemmy. We don’t want to deal with karma farmers and minimal karma requirements to post. I don’t care about the moderation issues because karma brought more harm than good. Please never add that bloody dreadful thing to Lemmy. I already saw a bunch of people supporting adding karma to Lemmy, which will turn Lemmy into a cheap Reddit clone and karma-farming hell. Please, never add karma to Lemmy. I beg you. No more karma hell.
While I agree with most points I’d like to give a reason why a voting system can be a good idea. It is a way to filter interest or engagement, posts or comments that got a reaction are likely more interesting to other users as well. And another argument is that it gives perceived value to an account, meaning people will not spamm accounts and banning someone has a perceived consequence. I don’t moderate any community so I don’t know if that is effective but I feel like thats a reason for keeping a version of that around
