Just tried this with a few auth codes from Autofighter/kminer, going to leave the websites minimized for an hour and then we'll see if I get some codes Thanks for tutorial, great find.
I wonder if there would be a way for one of us (or many of us) to create a vulnerability checker for this potentially very profitable trick, that could either check through an entire list loaded from a text file or actually scan through search engines with manually driven keywords.
