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.
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.
