sucker list

Here's a new scam they have out to go along with all the others. You have just won the lotto but its in another country. Why they want you to send all this info,they can get all they ask for by going to a research page type your name and you get it all.But going through all this for only info I don't understand.And there's another that tells you that they want you to pose as someone else to get millions that's in another country. Is this to get people to come to thier country or what?Are they that hardup on people to come there?
