Maybe the app is hitting the rate limit?

It looks like it started hitting abuse rate limits, which I'm guessing happened between adding the label and posting the comment:

 {Error: {
   "documentation_url": "https://developer.github.com/v3/#abuse-rate-limits",
   "message": "You have triggered an abuse detection mechanism. Please wait a few minutes before you try again."
 }}

There should probably be some throttling for when an integration is first installed.

@rafaelfranca also, I'm excited to see that Rails is using this. I'd love to hear any and all feedback.

Yeah, a throttling should fix the problem. So far it is working really well. I'm happy to retire my manual script 😄
