I agree with Aurafire - voted No.
Perhaps warn him, officially, to limit the posts he makes on a specific topic (i.e. Anit-evolution, Para-Archeology/Geography/History (or whatever), Random Psuedo-Science etc) to a single thread (i.e. One Topic, One Thread), on pain of Ban. That might solve the clutter issue. This warning seems warranted due to all the complaints regarding his spam-like posting habits.
Just my 2 cents.
