I understand the point of view that they cannot go after everyone. I go back to my point regarding Anonymous and one it's peoples attacks a major online payment site. A free program was offered to ordinary folks for download which allowed the "horse power" of their systems to be used in the attack. The program
itself ultimately, (through some manipulation and also some fairly poor coding), allowed the U.S. FBI to list the
ip's of those who had downloaded and used the program for the attack. They then tracked down some of those who had taken part in the attack and prosecuted them successfully long after the event was over. This is a synopsis of a fairly long and more complex series of events but essentially accurate.
The main point is this, if a Demonoid user was not employing any safe guard for their identity, it is entirely possible that they are compromised. The government doesn't have to go after everyone they can simply make examples out of a few chosen individuals and publicize the hell out the resulting sentences to scare people away from "fair use". Why make it easier for them, why be complacent about security?
I am not saying run screaming into the night but be aware.
