thousands of $1 charges and refunds in a 7 hour period seems unusual to me. then again, i've never run a site that received thousands of charges ever, so seeing it in a few hours would be obvious.

		Genuinely asking, are you a product manager? You’re giving me flashbacks to all of the PMs who suggested a 2-3 branch decision tree for a complex classification problem, because that’s what struck them as intuitive. We are just a few baby steps away from reinventing the entire field of fraud detection within this thread.
