this is a perfect example of premature optimization. same thing happened to me. i'm not sure how you could screw up a web app this simple. they seem to have gone in and tried to institute some form of rate limiting, and it's actually kicking out legitimate users with that error, now.

I'm getting the impression that it's not rate limiting, it's just running out of questions since not many people are asking them. It says something like that, and even if I fill it out slowly I never make it through.

It's most likely a bug. "Go outside" is intended to come up when you've answered all the quandaries that need answering that you haven't voted on yet.
