Sure, recently their service seems to have degraded somewhat. But that's orthogonal to what the expectation regarding the judgment of the provider. None of the major players have ever presented their service as a free for all, to do whatever you'd like with. There have been abundant boundaries outlined in the ToS of all providers that I'm aware of from day one. So the expectation then is that they might choose to exercise their judgment regarding your queries, and that they are inspecting them in some way (fully automated or otherwise).
