Playgrounds have bullies, and the Internet is one big playground

“You have the right to remain silent. Anything you say can and will be used against you in a court of law...” The legal rights of the accused are familiar phrases to any T.V. watcher, but few people know Internet copyright law. Perhaps users are too reliant on the computer to verify that they make no illegal move, as in a game of solitaire. It may also be that because they do not see a traffic cop to keep them under the speed limit, they believe that no such limit exists. Whatever the reason, general ignorance of copyright law is exploitable. Knowing your Internet rights leads to two things: One, you will not break the law. Two, you will protect yourself with it.
