Sure they are. Echelon is real, and at least in my country the military intelligence monitors all internet traffic across the border. I would be surprised if it wasn’t filtered by some other countries intelligence as well, but even if they weren’t they share relevant data with each other. It is awful of course. We couldn’t stop that in our country and I wonder if there is any point of resisting these things sometimes. They do it anyway. But, I doubt my post here would be analyzed by any service just because I write Osama. Which by the way, I find is most likely dead. Not that it seems to matter much anymore.
