Curt, I may have to resort to that. I haven't, since I thought it would be a good idea to receive messages from them that dealt with either problems or specific updates to the program I have. Typically, such messages would come once every few months. But the constant barrage usually has nothing to do with the program I have. Even if it did, the frequency would be oppressive. To be honest, I was surprised when I tried the program (quite a while after I got it for free, probably via GAOTD): I assumed from the absurd number of emails that it was a piece of junk, but it turned out to work quite well. They're shooting themselves in the foot, I think.
