Colin Temple, I doubt that assertion. Unless every single person who has immigrated and settled in the US is in the scamming business- for it is quite, quite obvious that English is not their first language. (I like the offer I got this morning; it says: 'Real Men in bed all the time please their woman'.)

Most spam, as far as I can tell, may easily originate in the US. That, however, is quite separate from Scams.
