This is not fair to OP or others who as you say "game the system". Using all benefits available up to the legal terms and conditions is simply following the terms and laws, it is not gaming.
Amex allowed one to refer oneself until recently (only last week did they update their terms to disallow it), they allow having multiple cards, they allow exclusively bonused spending and so on. If amex doesn't want us to do something - their team of lawyers should add it to their terms.
