Users' aggregate post and comment score has been entirely removed from the Lemmy API (as of version 0.19.0 if I remember correctly). It is not easily accessible to anyone, including admins. You could write a script to sum a user's aggregate score.
Thanks. I love that we’ve got several active alternatives we can communicate with on the threadiverse now. I like Lemmy but I hope they continue to proliferate.
Well, in that your upvote total and ratio can be calculated, at least. Does it actually do anything, or can it do anything, like it did on reddit? Subs having minimum karma thresholds, that sort of thing? If not, it's truly meaningless and can be safely ignored by everyone.
