This doesn't sound very scalable. You're almost certainly overcommitted on the upstream side and likely looking at congestion if many customers are spewing.

If they're spewing spoofed traffic I'm dropping it, so that's not a problem.

What do you tell the customer who calls and complains that *he* isn't a major
traffic source, but he's seeing dropped packets and delays on your upstream
link?  Do you tell him its full and they can track down which other customer
is the offender?

Do you usually design networks that can't handle customers using what they have paid for? I don't. (for any reasonable amount of statistical oversubscripion of course)
