You are correct, it is pointless to attempt to keep up with people that will try to avoid a system. But, that is the entire point of his project and not the part of our puzzle here.

If he added the words "t h i s" to his wordlist, they would match, without the overhead of running every word through thousands of permutations. Point being that whatever algorithm he comes up with could be applied to the wordlist ahead of time, thus removing overhead during execution.

But I agree that people will always find a way around these systems, even if it's only for the pure fun of being better than the system. Everyone else in this thread has made the point already, I won't waste anymore keystrokes reiterating it.
