Well the only people who can compel you to do this sort of thing are the Strassenverkehrsamt (Motor registry office / department of vehicles, etc). So, given that the the place you land up doesn't exactly look official, I think you can be sure it is spam.

I also suggest you remove your email address from that post, unless you want to turn your spam trickle into a flood... I don't know where else you use that email address, but if you've put it out in public on this forum before, then there's a good chance it was lifted from this forum to make that spam.
