To me it just screams naivety to put up a free service, advertise it as unlimited and then calling people asshole when they make too many requests.

Personally I would never rely on a service like this since it's 100% obvious it would be sudpectible to junior developers misunderstanding what is reasonable usage.

If you're putting up an API assuming all consumers will consume it in some limited and reasonable way, then you need to rethink things a bit.
