Okay, I agree that it's not entirely without merit, but realistically joe-blows personal page is really not likely to be on the first page of results without a pretty targeted query. So you've got to weigh the probability that the recruiter even finds the personal page, that is even has any effect relative to the negative thing, vs the potential harm of being out there.

I don't think the cost/benefit is likely to pan out. Of course, on the same basis, blocking yourself out of google results is also mostly irrelevant for the purpose of standing up against DRMing the web.
