Phone number risk scoring models would heavily weigh against behavior like that. Prepaid numbers are typically scored worse than post paid numbers as well, but that sort of behavior would quickly be identified as fraudulent.

This assumes there is a way to tell which numbers are prepaid or not. To the best of my knowledge they both originate from the same pool of numbers and it is impossible for an outsider to tell whether a given carrier's number is prepaid or postpaid.
