Even that probably would never work. Bruce Schneier was saying that someone had uploaded a fake "Bruce Schneier" key to the keyserver years ago (this was about 2 years ago that he was telling me about this) and he tried for ages to get it removed. As fast as it would be removed, the other keyservers would resynchronized and add the key back. Unlike pokeymon, he couldn't catch'm all. Since he didn't have the private key, he couldn't revoke it either. :-( Catch-22... How do you get rid of something like that in a way that doesn't open up a door for other people to create denial of service attacks (blacklisting)? No answer...
