I am supposed to be taking my NHE Master Trainer Exam in a few weeks. I am questioning their legitimacy. Any info?

I am seeing a lot of message boards that appear to be EXACTLY the same info about someone taking or scheduled to take a test with reponses by people saying that they are questioning the authenticity because they failed or sre not smart enough. I don't care about pass or fail. I am wondering who this group is. If I google them THE ONLY THING that comes up are the message board threads and scam reports. Obviously this is a red flag, but maybe I am missing something? Is anyone actually employed by them? Why can I find nothing about them online?
