Nigerians have been king of doing this.
It has been a good while back, But a Nigerian ring was running the inheritance scam in England. Making big $$$$$$$$$$$$'s , Mainly off of the elderly and extremely naive US folks.
The South Africans know how to cash in on the weak as well, Usually them being ladies praying on lonely US men.
I defiantly have nothing against Nigerians or South Africans, I have friends that come from both places and live here in the USA.
We have plenty of hustlers here in the USA, They just can't pull off their gigs on the web, They know they will get caught that if thy try.
The real lottery, Well, I play every week, The best i have done in 20 years, 1 ticket got 5 out 6 in my state lotto, Paid me 2,900.00 , Better than a swift kick in arse. I haven't won any thing over $5 in a drawing since.
But i will keep playing, I only play $4 a week total, That for Powerball, My state lotto.
