Check out this article that Born to Live put out. It is about a legal action taken against some websites that sell actual exam questions.
Microsoft sues over certification study guides 'identical' to exams
In the article it talks about how Microsoft cannot find out who the owners are. This does not make sense to me. They write the software that is being used on these sites, they know all the holes in it, they should be able to find out who the owners are. It might be considered hacking but who doesn't do a little hacking every once and a while.
I hope that they find them and put them out of business.
In the middle of the article there is a paragraph that was interesting to me.
"The company says it wants monetary damages, wants all the profit the defendants allegedly got from their practice tests, wants injunctions on the study guides, wants the Web sites shut down and transferred to Microsoft's ownership and wants the defendants' bank accounts frozen."
If Microsoft gets the website ownerships they could use them to find cheaters by putting out mis-information and tracking their progress and decertify them.
