We have determined, 179 questions too late, that we positively need to kill an ambiguous bad tag, and kill it with fire (= remove it from all questions).
How can we:
- Ensure no questions would remain untagged as a result of this operation (I only found two questions that only were tagged with this tag, those probably had the other tag auto-pruned...)
- Actually apply fire on tag?
- (bonus) Blacklist it, at least for a short re-educating while?
