for Lemmy users there doesn't seem to be a running, total tally the way there is on Reddit.
To be honest with you, I would rather kbin's karma be handled in the same manner that lemmy handles it. I see no reason for it outside of sorting. Communities could lock the ability to post behind a minimum karma like reddit did, but nobody can really pretend bots won't just get around the limit by reposting a single picture of a cat.
I sense by far what having a visible reputation on a user's profile is going to lead to is just a bunch of karma farming. The low-effort reposts, mindlessly repeated one-liners, and constant bitchy one-upmanship are all things I'd be very glad to leave behind me forever. I didn't even realize how bad it had gotten til I left, and now whenever I end up back on reddit for something, the whole thing just makes me tired. I seem to have been a frog, boiling alive in mean little shitposts.
