Actually, it is particularly easy to be anonymous on the Internet - more so than through any other medium in the world (IMHO)

There are perfectly good anonymous file sharing apps whaich are gaining popularity at an incredible rate due to these disclosure decisions by the courts. Using them, the only thing that can reasonably be proven is that you are using the application. It is not possible to prove what you are sharing or downloading, or even if you are doing anything with it. Very neat.

Or you can very easily spoof your IP address - there are ways of routing your connection through various hosts to obfuscate your real location - just got to watch 'Hackers' for a demonstration
