Hi Chris,
I've viewed the website facepirater*com. They're not asking for payment anywhere that I've seen.
The most questionable thing I've seen is of course it's a hacking website for FB. It won't actually hack anything. They're asking you to call a phone number, which won't do anything. (Except maybe charge you high fees? *Don't call the phone number)
I don't know if you've actually called this number and found out what they want - but it's sufficed to say that people looking to "hack" a Facebook account are probably looking for a one-step click fix. Not a multi-step hack that involves calling people.
I can think of far easier ways to gain someones credentials. (Programs exist to do this. Chrome has historically saved "auto-fill" passwords in plain text. I'm not sure they still do, but I wouldn't be surprised.)
So, it's not a phishing website, but it's not something that Avast! should be allowing either. (Given it's questionable nature)
