He did it because he enjoys notoriety. Those things hold value for him. Which it did give him notoriety. Unfortunately too much. Just because you don't value internet cred, doesn't mean he doesn't. I think the difference of why you think he is dumb is because you think it's stupid to value internet cred. Which is subjective, but irregardless, there is a low chance of him being able to achieve the success he acquired by not being reasonably smart.
