There’s some misinformation floating around regarding Lemmy not having a karma system. While many have discovered otherwise, this is for those who may not have.
While it’s not exposed in the Lemmy default user interface, Lemmy does have a fully functional karma system and it is visible in third party clients such as WefWef and Memmy.
Do with that what you will.
I know my comic praising lemmy for no karma added to the confusion on this but I do appreciate that lemmy.world does not feature the server karma on profiles for reasons already said in the comments. Thanks for clarifying.
