Yeah he shows some tell tell signs that he has a mental issue going on. He stalked me on another platform, (I don't hide behind a handle) and he continuously tells people the same lines from video to video. "You are a liar", "You don't have an argument", "I know but you don't" over and over again. No matter what the people comment he is going to tell them they are wrong, and everything he knows. Keep in mind: never knowing who is on the other end of the comment.
When asked what makes him qualified to tell people he knows more than they do, he resorted to stalking me instead of publicly announcing it. He also said Hornady posts all of their testing on their website. Being a development scientist for a while, I know that is a lie, they all do proprietary test when doing R&D, and the people who do those test are bound by contractual agreements.
I shoot bullets of all manufacturers, and don't usually pick one to go with for everything, but one thing you won't do is lie, and then try to cover it up. That's the only part I was there for, to catch him in his web of lies. Completely independent of what manufacturer, it's a question of character and honesty. Calling out a company for something and then being caught in a web of lies doesn't bid well for your credibility in the gun world. Which is why he started hiding comments and deleting videos when I put my throw away email out there for people to see the screenshots of all the comments he hid, and the user handles that were also blocked. It was all fun and games until people started viewing the comment thread on his previous videos and couldn't see the comments that I can see. He couldn't back track it far enough once people started emailing me and getting the screenshots, because at that point he had publicly said "those were taken over different days", AND "The only comments that were removed were from people who blocked me" (which is also false) when they show you they were taken on the same day. Not a single one of us had blocked him, we could comment on his post, they would just never show for other people.
He tried to use the line of "oh I have screenshots too", but that backfired because since he is the OP of the video, he is also the controller, and can see all comments even if hidden. The true test is to send someone who has never commented and never viewed the comment list. That is the ultimate test, because what is visible to that user is different compared to comments visible to users that had comments hidden.
Already told him he can't hide in the digital age, there are digital copies of everything shared on social platforms.
