Are people notified when you block them on Twitter?

[Matthew]

For privacy reasons, and to protect my reputation, I have blocked someone on Twitter. My brother says that blocking someone on there is not just a private act--he says that the person I blocked will receive a notification saying that I...(insert username) blocked them. But that can't be true, because that's not how Facebook works...

And as a second question, are you notified if someone favorites one of your tweets?

So is that how it is or what?
