You are basically saying a feature that might be misused is bad! Lets instead assume the guy knows what he is doing and try to be helpful by pointing out the pitfalls of doing it this way. Maybe he has a well designed idempotent rest API with a working transaction model. Or maybe he just wants to use it for get requests. /Björn
