I recently found this Firefox extension that looks safe (I checked some network activity but DOUBLE CHECK) and brings back Karma on Lemmy!
INB4: if you don't like karma on lemmy, you are in good company. There is no need to hate the ones that do like them.
Of course being unofficial it's just a cosmetic feature, so it hopefully can be a funny thing without going to be toxic like on Reddit.
How much karma do u have?
