After a few hours of contemplation... I think I will have to mostly agree with nivlac.
Let's try to draw some analogies. What is the purpose of buying this software? To cheat. Plain and simple. There is no other explanation.
It's not like buying a stripper for a party, that has the "potential" to turn illegal in a hurry, but on it's face it can be kept legal. But propositioning a prostitute is illegal immediately with no chance to be a lawful transaction (in most states) which is why you can be arrested for 'Solicitation" of a prostitute, but not "Hiring" a stripper.... (when, in all likelihood, the same woman will be receiving money for the same acts.)
There is no reason to even attempt to buy this software. If you know of it's existance, you should, as nivlac pointed out, send the information to WGT immediately.
Another analogy.... Why would you go out and spend $6000 for a pound of marijuana? Just having it is illegal, using it even more so, and if your intent is to sell... it gets much worse. Would you just buy it to look at it? No.
Bottom line, in my opinion, is that if it can be proven that someone tried to purchase or use a program that would cheat this game, their account should be banned and their IP addy blocked. Permanently.
There is no middle ground.
It's not like buying a gun... guns, for now are legal. Yes, they can be used in crimes, but for the most part, most gun owners are responsible citizens.
