On June 19th, the meta tag error was burninated with righteous fire. However, it seems that this step wasn't quite enough. Someone recreated it yesterday, and there are now over 20 questions associated with it.
While it will be trivial to simply edit the tag out of those questions, the tag itself should be destroyed, blacklisted, nuked from orbit, made obsolete, murdered, obliterated, or perhaps banned.
Or something to keep it from coming back to life.
