If you think you have found an example of copyright violation you should leave a note at the Village pump.
Everything on Cunnan is under licensed under the GNU FDL. The gist of the GNU FDL is that the information is made available free of charge and can be further distributed in any medium so long as Cunnan is given as a source and receivers are given the same rights. Derivative works also fall under the same license.
You could print and bind (at a profit, if you liked) the entire contents of Cunnan but you couldn't stop people from photocopying the bound copy and selling that.
