I know the obvious things like federation and fediverse, but do we say upvote/downvote, updoot, karma? I hate to bring up the software that must not be named, but I don’t know what else to call things.
You subscribe to communities, which are hosted on different servers. Upvotes and downvotes are what they are. AFAIK there is no karma counting here.
Lemmy once computed a total score internally, but this was removed in the later versions. There is no such thing as overall user karma or score unless an admin or other software decides to try to compute one. The platform itself doesn’t care.
Here are some examples of “other software” that does compute this.
Mbin still reports the raw reputation score, e.g. https://fedia.io/u/@henfredemars@infosec.pub
Piefed instead reports an attitude percentage, e.g. https://piefed.social/u/henfredemars@infosec.pub
Both do so without requiring an account.
Some apps/front ends/instances track upvote/downvote totals. Haven’t run into any automated filters based on total karma yet, though.
Also worth mentioning that instance admins and some moderators can see specific users’ upvotes and downvotes.
There’s also a public mod log where instances display their moderator actions taken against whom for what reasons. Doesn’t quite stop moderator abuse but it makes it public.
Any kbin user can see everyone who upvoted something. They used to be able to see all of the downvotes as well, but that was disabled with most kbin instances…
As far as I know, all you need to do is find a kbin instance that allows their users to see both upvotes and downvotes (or set up an instance yourself).
It’s best to treat your votes here as public if you’re coming from Reddit where you normally expect this to be hidden.
