 Replying to [comment:14 azazar]:
 > It will fail, unless someone is able to bruteforce secret for
 `facebookcorewwwa.onion`(which is resolved from `facebookcorewww.onion`).
 And this isn't easier, than bruteforcing hash for
 `facebookcorewwwi.onion`(difficulty of those tasks are exactly equal).

 It will fail, after querying all of the HSDirs for a non-existent hidden
 service.  This is a waste of network resources.
