I think you are misinterpreting what his posts are about. From looking at his blog, his posts are mainly a lets play style. Your background as a 'competitive gamer' means nothing, because his posts are to provide entertainment. You don't find them entertaining? Then don't watch/read them, it's that simple.
If you think he's being paid too much, then you can flag him. But enough people find value in his posts that they are willing to use their upvotes there. Being skilled as an entertainer is quite a valuable skill that you seem to be completely overlooking here. Who are you to judge what skill is more valuable?
