This is a pretty cool idea. I am also seeing that kbin seems to keep track of what it calls a “reputation”. So we can theoretically have tools that try to aggregate publicly available data to come up with a reputation score, even if lemmy doesn’t provide it natively. That would probably have something that a lot of mods would want, but it would be helpful for users too.

This tool and system will probably show up whether it is native to lemmy or not. I can imagine a scenario where how much reputation or karma matters is up to each individual instance. It would be cool to have a system that browses in “civil” and “unmoderated” modes honestly, I would probably enjoy that, and leave it up to the users and owners of each individual instance.
