As a follow up here -
Yes, we do understand that for developers, any level of vagueness regarding the precise details of policy enforcements are difficult to deal with and specifically, to code responsibly for. This is one of the issues especially when talking about our adaptive posting / write limits for API actions. As a developer myself, I get that it would be far more understandable to provide direct metrics or enforcement algorithms!
The issue here is that by being completely explicit about the boundaries, the bad folks will be digging in for loopholes. However, we know that the vast majority of responsible developers and application owners also understand that the platform needs to be able to adapt to unexpected circumstances and bad actors, and we thank you for your understanding in those situations.
