Input sanitization and bounds

[abrad45]

If your loan is seven figures, should we bail? Should we ask for patience? Should we profile the code and cut down on bottlenecks? At what point do we decide we've gone too far and start worrying about people blowing up their browser? You could technically go in here and say you wanted to pay off a loan for $1,000,000,000,000,000,000,000,000,000,000, at a 1% interest rate and pay $1,000,000,000,000 a month or something and I guess it'd work as long as you pay more than the monthly interest. Do we really need to do that?

I'd say we should cap the principal at $250, the interest at 10% and the monthly payoff at $2000. Are there loans that charge more than 10% interest? If you miss payments or defer them or something?
