Again you mention being upset. I'm not upset by any of this. I don't think anyone would be. But you're just not in the demographic of people that most people here would need to show evidence for.
I've mentioned before: I've learned from people who are professional and amateur kickboxers, and from people who have won bb naga tournaments. I have no need to prove that to you. And it's not my place to, if my instructors do not want me sharing their info online (which I haven't asked them about). You're the same. You've mentioned learning from UFC fighters I believe, but I don't recall you ever mentioning who.
If I make a claim and say you should listen to it purely based on my instructors/lineage that absolutely you can say it is false. But if I make a claim about a technique, and you really want to learn, you have the chance to test it out for yourself and see. And then we can have a rational conversation about it, regardless of my lineage, or my MMA/kickboxing score, or anything else unrelated to the technique.
@skribs is a great example of this. You mentioned the inverted backfist recently; he didn't think it would be powerful. He tested it out and found out that it is. I expect he'll test it out more in the future. At this point it really doesn't matter if you are lying about your credentials or not, you gave him something new to think about.
And at the same time, he has no need to prove to you that his style works, because you aren't going to be a student there. But if he mentions a strike you haven't heard of, just like you did to him, and you dismiss him based on him not providing that evidence to you, you're really only hurting yourself.
So again if you worked on your own arrogance. And became openminded the way skribs did when you offered something new. You have the potential to gain, and no potential to lose (to take the skribs example again: If he did the experiment he stated in the other thread and found that the inverted backfist sucked, and didn't practice it any further as a result, he really wouldn't lose anything from that).
