Wait, so their solution to fraud is "send us an email and pray something happens"? Neat. If I could trust this thing less I would, but the word "Facebook" in the name already pegs it at zero, so... Hard pass.

And about storage, ok, read this:

Anti-fraud technology monitors purchases on our systems to detect unauthorized activity. Your payment method is not shared with buyers, sellers, or merchants without your consent, and is stored separately from your account data.

And tell me it doesn't say all payment data is stored on FB servers and mined by all their algorithms.
