Although the system won't ask for your name, you need to provide use cases. If the use case is vague, the "generic" answer you'll get will be useseless, and if it's precise enough to allow for the correct "generic" answer one would presume that it makes your identification trivial. Hard to see the point then. Especially as they promise a "generic" answer, i.e. a non-binding one... and also it's unclear whether they would consider anonymous question to be proof of good faith.
