Only a handful of questions tagged [errors]. Perhaps retagging those so the tag goes away "voluntarily" would be enough, without blacklisting the tag?

Yes, exactly. Maintaining individual faq images for each site would be a bit of a nightmare. Sketchy is pretty simple and since all sites start with it, possibly easily recognizable. We used the bicycles site as any content that makes it into the images is going to be safe and understandable to most people.

Since today! (:
