On my profile page, my newest badge was shown: Cleanup. However, it linked to the wrong question; I actually earned it for rolling back the vandalism in this question. The link on the badge page itself is correct. The wrong question has a very low post ID (6) which I think is not a coincidence.
Right now, it can't be verified anymore, because my newest badge is now Quorum, which – oh, the irony – I earned with this post.
