How to unlock our tests on webpagetest.org

[nocompiler]

Hi Team Webpagetest,
We run some automated tests to get the performance of some of our pages.
Recently our requests were blocked by webpagetest.org with message "Your test request was intercepted by our spam filters (or because we need to talk to you about how you are submitting tests)".

Can you help us how to resume our tests. We fire 12 tests for 6 urls (both for mobile and desktop user agent) every 30 min. Following are the keys used by us to prevent from exceeding total limit based on per key.

Let us know, whats the way to pass through this. Do you want us to reduce frequency? make it to 1 hour?

Thanks,
Rahul Kumar
