In this specific case I'd recommend burnination.
As already mentioned by me in a comment to this meta it's probably a better idea to remove the possibility to find this tag on google and remove any other historical occurrences of it. Old questions that are closed and have no good answer will be deleted by the system anyway (unless they have been voted up enough), so the historical value of these questions is very low.
Why not just blacklist it?
- people would still find it on google and we get traffic we do not want (Off-topic posters; they could just post questions without using this tag)
- If we later allow it to some extendextent it's easier to re-create (no staff interaction needed afaik)
