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.
Should probably be a per-server karma system. Or else anyone could create their own instance and auto-give themselves enough karma to be “trustworthy” and set their account date.
Definitely seems like that would end with defederating that server
Good luck detecting it
