Yes, definitely sounds like a scam. And performing an nslookup on
www.paypal.com shows all their addresses fall under the following:
216.113.188.*
And, according to Visual Route, the site they link to h*t*t*p:// 200.215.16.194/Agenda is located in Brazil.
I'm sure I've seen an address to report scam to PayPal - might be worth browsing their site to find it.
edit: also, why have a redirect from that topgsmfrance.com website...? Not very legit, either, imo.
