All that will do is make them less searchable, thus eliminating you from finding your stuff being shared illegally in the first place.

These sites operate on a "word of mouth" level.  Not being Googled is more of a boon, not a hinderance.  You think TPG would mind it if they couldn't be googled.  All that means is that he'll fly under the radar until someone snitches.
