I understand what is this opportunity (just read some other posts in forum that explain WHY they need only US citizens).
Probably is a good way to earn some bucks (not too much) but a good amount even, and you need to share with other persons (is not a scam / ponzi).
I will not explain what is this service just for respect to OP and other people from US that are earning some bucks with this simply method.
If you want us something illegal then I don't think anyone is interested but if its a legal opportunity then I m interested so plz provide me the details will check it if it looks OK I m in if not then you get one more negative from me
