Can a moderator please kill this tag?
I've deleted the old question, so the tag should just naturally die. I know this has been mentioned a few times before, but for clarity (and posterity) moderators can't just kill tags. That's something we need to ask the Stack Exchange team to do for us, if a bad tag gets out of hand. Otherwise a tag with no questions will eventually die off. So long as it doesn't become an abused tag it'll just disappear.
