I don't know how to figure out how much it would 'cost' to have human contributors spot embedded penises snuck into transcodes and then figure out which of several contributing transcoders are doing it and blocking them, only to have the bad user switch IPs and begin again. ... but it seems impossibly expensive even though it's not an actual dollar cost.
Standard solution to that is to perform each operation multiple times on different machines and then compare results. Of course, that raises bandwidth costs even further.
