I'm a little skeptical of this because tons of people use obscure URLs for delete links or confirmation links. Wouldn't people see tons of entries in logs of Google hitting confirmation links and havoc being created by Google hitting one-time links for, say, deleting a file? It just feels like one of those things that if it were true, would have already been at the top of Hacker News several times.
