So much stupid in this post.
They will work with a report system, as they have been doing it in a way, they seed a file like a movie, and see who connects to your client, basic honeypot. They see the IPs which they send to the owner of that ip, the ISP, which will send the warning to the user allocated to that IP or range of IPs and punish them.
They cannot disable bittorent since it is used as you say by Linux and other projects, also P2P systems exist in WoW updater, Star Trek Online downloader(and any other program that uses Pandoo media booster as a background downloader)
Torrents should not be used with Tor, too slow and its not optimized for this, would have a large negative impact on Tor. Torrents by proxy already exist, well rather they tend to use VPNs and seedboxes. These come at a price because it would be financially backbreaking to provide this to users for free since server usage and bandwidth tends to be expensive on a large scale.
The third parties will do as I said before, just make files a honeypot, they won't actually sift through all your mails, so nothing private comes out because this would probably violate privacy laws and the likes.
Also what the fuck, you don't even know what wireshark does, you can't monitor anything on the internet unless it passes through you. Wireshark allows you to see the connections between your pc(or if its installed on a pc between say your network and your ISP, it can see connections from anything behind your network connecting to the outside and things to connect to your network) and the outside networks.
Say if it its installed on your PC and you type
www.google.com in firefox, you will see HTTP requests going out to 173.194.34.66(google). YOU CAN ONLY SEE CONNECTS ORIGINATING FROM YOU OR HAVING YOU AS A DESTINATION. This only has one exception, if you have a WiFi card that can handle monitoring mode it can also see the unencrypted wifi communications going around.
This all will not determine users from using the internet, it is at a point its pretty much essential from most people, resumé needs to be sent in email, family needs you on facebook, friends need you on chat, news comes from online websites nowadays.
Over here, taxes are done online as well. People don't really care much about internet privacy when it comes to the average user because they don't understand the dangers of it, they'll just go like OH YEAH IT GETS RID OF THE PEDO WEBSITES.
I am against censorship, just needed to point out the retarded in your post.
