MichaelBlueJay - if the only barrier you have to crawling those ad links is JavaScript, I think you should add another layer now, rather than wait. Cursing isn't any good after you've already felt the pain.

You can, for instance, call the script from an external file that is disallowed in robots.txt. I'm pretty sure that is what Matt Cutts recommended a year ago or more, when this JavaScript parsing first started up.
