On the basis of the answer my previous question (and the SO blog post linked to therein), I've bulldozed all homework tags from questions on serverfault. Anyone with the appropriate mod bits want to handle the behind-the-scenes stuff required to make the tag go away completely and forever?
Looks like the homework has zero questions now. If it keeps coming back and you can't keep up with it without blacklisting, feel free to make another meta post. Thanks!
