But the author also intends you to provide the source when you distribute binaries.
So in that case we can host the sources ourselves? I don't know if it'll be right to do so..especially if people start downloading from there instead. Legally, the GPL allows and encourages that. Also, the author cannot take action but he _can_ blacklist people on his own papers because in that particular situation we are not helping him. That's what I'm afraid of.
