Throw up a 410 header when you detect Google or another bot on those
pages and the bot will be tricker-ied into removing it stat.  They don't
joke around with them 410's. Mostly because most software for the web is
too lazy to differ (or just doesn't know the difference) between 404 and
410 so when those bots see a 410 they assume you know what you're on
about if you're using it and do as you want. You should also consider
adjusting your meta tags and adding another:

<meta name="googlebot" content="noarchive, nosnippet">

It'll pick up the rules in your other generic bot meta too. Adding that
meta tag will be worthless if you pass Googlebot at 410 but it's still
worth it to add if you plan on keeping it the way you do.
