Does anyone have a positive opinion of Aaron Cleary's YouTube videos and books NSFW ?

I have heard bad things about him and his youtube channel. Does anyone from Fluther like him? I find him hilarious. His site is called the assholeconsulting for paid advice. His material is NSFW for swearing . Also is what he is doing legal, he doesn’t have a license? Could others copy him and start giving advice for profit?
