Evilore is just scared and/or believes the challenge is beneath him.
Yep. You're either interested in the challenge, or you're not. And if you're not, just say so. EXCEPT (to engage in some rampant speculation) he's built up such a "zen master" persona to himself and among his followers, that he probably feels he can't just say "naw, pass." So he throws up money as an objection.
If it was really a desire for it to be a money-making venture, he could certainly throw some promotion on GAF for it, I'm sure lots of people would throw money in a hat there. Except then it becomes a "big deal" and he stands to lose even more face should he lose in embarrassing fashion.
But, I mean, even lowtax had the balls to get beat on by Uwe Boll for a round.
