Implementing the patent system's own controls is the best approach to repairing this situation until congress decides to take the problems of software patents seriously.
The EFF approach solves the problem for everyone by having the patent office void the patent due to prior art claims.
Adam's approach inflicts financial pain on the patent holder.
I don't know what your copy of the Constitution says, but mine says:
"To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries"
The troll in question is not an inventor, has made no discovery, and is doing nothing to promote the progress of science and useful arts.
I'm not saying they deserve anyone's sympathy. Objectively speaking, of course, most lawyers are doing pretty well (though there's this: http://www.cnn.com/2014/01/19/us/lawyer-suicides/). But I don't see how there's anything wrong with somebody paying their fees. They are earning them, after all.
