OK, I am going to bite. Why does @eviltrout have a garbage man badge?
And why does the badge only display on his user card, and not on his user profile page? Or on the badges page?
I categorized as a bug since when you click on the badge, it goes to Discourse Meta which is an empty page - probably not as intended.
I am interested however in custom badges like this - would be interesting to display for example organizational affiliation with details synced from wordpress via SSO.
