Now I know the initial post was a troll job. But some responses confirming it's sentiment I'm not convinced are trolls. So I shall relay a quick story.
I was a BJJ whitebelt. Never got past BJJ white belt. Trained for about 9 months. Anyway, there was a guy at my work who was self taught. He had training manuals with more moves than I ever knew. He studied fight footage and ordered training videos. After years of practice he had designated himself approximately a brown belt. I have to credit him that in doing drills, he certainly did know tons and tons of submissions I had never even seen before. Anyway, he also taught classes (not like at a studio or anything, just anyone who wanted to learn they could come over and he would teach them). So one day the other guys at my work tell me I should come to his class because he is "hella legit." So I go, he is teaching me some stuff and then it is the end of the "class" and it is time to spar. I tapped him in about 30 seconds. Repeatedly.
I've done boxing for years and I've had numerous friends ask me to teach them. In the past I use to oblige, but I eventually realized something. They would come over for a lesson and I'd start teaching them the stance, and the forward and sideways movement and have them drilling on those things and eventually they'd say, "No, I don't want to learn all this, I just want to learn to box." It was then I realized they wanted to learn only how to throw a punch. I can teach them how to throw a punch, but that isn't boxing. And no matter how great you get at throwing a punch, it isn't going to help you against a good boxer unless you know how to box.
I find the same to be true of people whom believe they are learning submission fighting or MMA from watching it, or reading a magazine etc. But I've had people ask white belt BJJ me to teach them BJJ as well and the same phenomenon happens. They don't want to learn BJJ, they want to learn how to arm bar. And that's what those instructional videos usually teach "here are a bunch of submissions." But listen to the corner men and the coaches whom are always screaming "Position before submission." That "position part" is the hard part to learn. Submissions are easy. Being good at getting position takes thousands of hours of practice and you can't learn it by watching MMA.
