I think salty wins the all time "most proclaimed exits" award. I think he even claimed he was insulted and leaving after his first post..he then continued for about a month.
Syamsu could win the "how did I end up here?" award. I think he was looking for a website on detergents, only read the first two words on the site and then assumed he was in the right place because somebody in the laundromat may have told him so. Besides, Darwinism is clearly suppressing the debate on detergents based on ideology. Some guy called Dawkins said something about selfish jeans.
