Facebook: Please fix this security loophole before its too late (salt.agency)

The issue has now been checked & confirmed by Guardian - http://www.theguardian.com/technology/2015/aug/09/facebook-p...

That's a regular feature / intended behaviour of the FB search. It's quite useful to be able to search for people by their email address or phone number IMHO.

Isn't a search (or querying of data) analogous to this one which landed weev in prison?

1) Generate list of possibly valid numbers 2) Query service to determine something 3) Get prosecuted 4) Go to jail

Just wondering...
