Yo, this feature is really cool. I also see it on Misskey

But sadly, I don't have drawing skill to make a lot of nice badges for it

I still agree with this. I also genuinely think they would be helpful inside of Reddit style communities. Or like nostr-based tech support forum but I think that goes along with the rep system that you were mentioning. (Ie A user gets a bunch of upvotes on a various number of posts for being helpful so they get a badge saying that they're not a total doofus or something.)

💯 agree about gamifying onboarding with badges from official sources etc. however, i like bitpopart's badges because it's good art. so yeah, there's that too

Badges are just as useful as nostr community admins from reddit...
