I don't get the OP's story.
Since when do the merchant (FB in this case) flag a CC transaction as "suspicious"?
The merchant asks for an authorisation code to the CC issuer. Once he gets it, he goes ahead with the transaction. This is in actual fact done all automatically without human intervention.
If Amex has a suspicion, they won't issue the authorisation code and contact the card holder for further verification. Such CC verifications are none of FB's business.
What FB cares about is if the FB account is not hacked, if the miles are not bartered or anything to do with the fraudulent use of FB account and miles.
CC matters are for the card issuer to deal with.
