You mean...when you go to that website and type in something, they can't tell whether you are typing in your own real password, and what website the password is for. Of course, maybe the website hacks into your internet's files to see what websites you go on.

The whole fact that this website could be a "scam" could be the fact that it tries to calculate how long it takes a PC to crack your password. That in itself is kind of vague. Or maybe the "scam" thing could mean that the calculations are inaccurate?
