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.
Unlike other Bethesda games, In Fallout New Vegas there’s a karma system that tracks your reputation among various factions, you can help and have good karma with one group of people and consequently worsen your reputation among other opposing factions.
New Vegas isn’t a Bethesda game.
