Well, speaking from my experience I was pretty clueless when I first started using the Internet.  I visited a lot of sites that I know now were ripoff sites.  The Internet was something full and free and anonymous.
It was only though reading conversations here on this message board, through talking to the artists and developers, through reading all the threads on rips and copyright theft and file sharing that I started to understand.  If this place had not been as friendly as it was, if the people were not as gentle and understanding and caring I might not have stayed and then I would not have learned.  Because one thing I know for sure... there are a lot more opportunities out there to take things from the easy way than there are places that take time to educate, support, and share.
It's something I remember sometimes when someone clueless comes along.  I have a better chance of getting them to understand things and change their thinking and habits if I take a little more time with someone.  I can be a real grouch sometimes and I try to remember that when I am responding to people.
Jafo's right.  The ignorance and indifference abundant in this virtual world does hurt real people, abuse their rights.  And its not easy to figure a way to reach people with some insight on their actions.  But the longer you can have contact with them, the friendlier you can be, the more approachable and therefore more reachable they will be.  Nothing makes a person's defenses to go up faster than to be met with immediate suspicion.  And getting through defenses is really a hard thing to do.
