Actually, no. I don't think that's the ulterior motive at all. I think percy and the rest of the EvC ruling class just want randman to improve his reading comprehension skill by putting some responsibility on his table.
I can't remember the last time when randman actually answered every point without trying to dodge the questions or focus on some tiny little thing (nitpicking) such that by about 3 pages later the main points have been lost. By making him an admin (giving him some responsibility), we are forcing him to actually address the important points that are brought up, not just hand wave them aside.
The other advantage of making him an admin is we are taking away his life boat everytime there's a big wave rocking his ship. After this, he can't fall back to the same old admin/evilutionist bias crap again.
I really think this was the goal for faith as well. No matter what she said, I am still convinced that she realized ahead of time how her lifeboat was going to be taken away and that's why she quit the game while being "ahead".
Anyway, I always love to read what people have to say about things, especially when there are at least 2 opposing sides. We'll just have to wait and see where this is going.
