I for the first time got to know about web seeds, these seed at maximum download speed your device can handle (like usenet) and if the torrent has no seeders at all these can be useful. I have seen their use in https://archive.org/ when I was downloading a Librivox audiobook. What are the disadvantages of web seeds? Would the government be able to shut these down with relative ease as unlike normal seeders, they are centralized. Also, is there a way to use these? I mean, is there a service which will seed through web seeds what I don't want to be seen seeding?

PS: Librivox is a free audio book site for books in public domain and you can legally get them after visiting their website. I love Librivox!
