Thanks to Phil, who commented my blog from a while ago, I finally caught up on this strange mirror website. It indeed is a spoof as they wanted 10$ for extension and email removal.

Here you can read it yourself.

The site is offline atm and I hope it stays that way for good.
Sites like that show up and die more frequently that one might think. That is why I hope the JED will reconcider its intentions on non-GPL extensions..  Or we might face another JED mirror that will pull it off.
