I'm unsure if you're sarcastic or not, never have I've used a ISP that would throttle you, for any reason, this is unheard of in the countries I've lived, and I'm not sure many people would even subscribe to something like that, that sounds very reverse to how a typical at-home broadband connection works.

Of course, in countries where the internet isn't so developed as in other parts of the world, this might make sense, but modern countries don't tend to do that, at least in my experience.
