Why do I keep getting notifications that I've reached my limit?

No one has even seen or submitted my form, yet I keep getting emails telling me I"ve reached my limit. Why?

I checked our mail logs and I can see that you have received several emails about reaching the API limit. However, your account does not currently use any APIs so you should not have reached the API limit at all. API limits reset every midnight EST, and since you are not using any APIs, you can simply ignore the API limit emails that you have received. This may just be a temporary glitch. Apologies for the inconvenience.
