Seen the OP's userid?

Hoot! Griminish is in the Outer Hebrides, about as far from civilization as you can get in the UK. If memory serves the nearest railway station is in Norway.

Now look at the OP text:

"...was slowly building up the AdSense earnings to approximately $2 per day."

That's almost an audit trail from a site violating the guidelines and ripping of Adsense straight back to an individual.

And it gets better yet.

That's consistent with the registration dates, and tells us that our scammer doesn't even know how to block the Wayback machine. The first version of the site even offers a cure for diabetes.

Now Google needs to do a little amateur data mining. If this site has been ripping them off at $2 a day, have any other payments been made to the same bank account?
