I'll try to be clearer:
Earlier in the thread, somebody posted about a tzedakah organization looking for people to sign up with their AMEX cards and the organization would register them and bill them. It had some funny language about cards with the same number.
I got an email from a different institution, using the same funny language about qualifying twice if you have a card with the same number as somebody else. When I asked the institution about this not complying with the T&C, they told me that "this is the info they received from AMEX."
I'm speculating that it wasn't AMEX that sent this info to either place but rather some middleman.
Anybody have any information on whether or not charities and / or educational institutions will be excluded?
