I added Have I missed anything from my list of web form best practices? to my Readability reading list, it gets sent to my Kindle (and displayed on the website) as:
This IP is only allowed to access our API.

I you believe you have reached this page in error, contact us.
As requested, I'm contacting you. I'm contacted Readability, and pointing them to this question.
(I'm guessing they're using one of the clouds, and you've blocked those IPs. Just a guess. But while I can understand blocking editing, voting, etc. from random cloud VMs, shouldn't anonymous viewing be perfectly safe?)
