Looking at your urlbox - pretty funny language around the quota system. >What happens if I go over my quota? >No need to worry - we won't cut off your service. We automatically upgrade you to the next tier so you benefit from volume discounts. See the pricing page for more details. So... If I go over the quota you automatically charge me more? Hmm. I would expect to be rejected in this case.
I’m sure we can do better here. In my experience our customers are more worried about having the service stop when they hit the limit of a tier than they are about being charged a few more dollars.
I would also worry about a bug on my end that fires off lots of screenshots. I would expect a quota or limit to protect me from that.
