If this was a legitimate attempt, then I give it a "FAIL" mark.

The solution simply doesn't scale. Just hope it's a legitimate effort and that people are wasting their time/energy on a useless endeavour.

Their biggest issue would be data contamination, either through fictitious names, or false positives. You could really just sit there adding names from the White pages.

The whole notion is ridiculous. Simply put, much like many other solutions that are proposed by Lefties, this will invariably fail, so don't worry about it.
