What's "strange" about pointing out that hands on the face is not the same thing as a poke in the eye? It's the truth. Im not arguing whether or not hes clean or dirty since that pretty subjective. What isn't subjective is that his fingers being in peoples faces is not the same as poking their eyes.
Yes, he touches the cheeks on purpose. The same reason Machida is doing this:
You outstretched hand can halt their movement or direct them somewhere else. It also obscures their vision. In Jones' case he's also taking advantage of a Muay Thai technique/stance that allows elbow strikes to land faster if the arm is outstretched as opposed to drawn back like a boxer.
If you want to argue that it makes eye pokes more likely and is therefore bad, go for it. Its an opinion and you're welcome to it. But you and several other people are saying he pokes people frequently, which is not true at all. His hands go in peoples faces constantly. The difference is obvious, but dislike for Jones is both common and deep which makes people biased. Once his fingers touch the eyeball, you have a poke. If that isn't happening then no poke is taking place.
