I find much of what Piru says to be 'intellectually dishonest'. I don't know if you (Piru) are claiming outrage over the letter of the law, or over the non-legal idea that ideas belong to people and shouldn't be used without permission.
If you are aguing the first, then to be anything but a hypocrite, you cannot be violation any other similarly laxly enforced laws. I highly doubt that is the case. Do you really refuse to sing happy birthday in public places? Do you show the same moral outrage when other people do? Do you make the same accusations against kindergarden teachers who read stories to their class as you do against CUSA? While it would take a lawyer and court case to prove, I'm pretty sure that reposting another persons artwork in it's entirety is still a copyright violation (as you have done), does not fall under fair use.
If you are arguing the moral stance, then you have already shown yourself to be a hypocrite by using other peoples works without their permission right here in this thread.
