Make sure you check their TOS before signing up / promoting it a lot. They do with with loads of countries, but do ban some big ones (the Philippines is one I believe). I read a post once about a guy who signed up using a fake address in another country, and then when it time to cash out, had loads of trouble getting his check because he was located in a banned country.
us -checkes cost me to much to clear in my country. Do they have other methods to getting paid?
