Attempting to "beat up a dead horse" to find its gone

I recently found a Youtube content creator that I enjoy watching; Kiandymundy. I usually browse the comments on youtube videos just for craps and giggles, and through a chain of comments from some of his older videos I found a whole debacle that involved Uberdanger, Gnarsies, and a bunch of other well-known League of legends content creators. I was vaguely aware of the whole thing when it happened, but when I saw all the videos and posts of various social media sites I was very interested. At the end of the whole thing was Uberdanger making a video apologizing for his actions and it ended there.

This is where it gets really strange. I recently was watching a newer Uberdanger video, (I watch most of not all of the more popular LOL youtubers videos they create) and I saw one of the comments on the video mention the whole Gnarsies/Uberdanger fiasco. Uberdanger then replies to that comment stating that the accusations Gnarsies and other youtubers were completely false and that they were just trying to get attention. This greatly confused me because of the apology video he made at the end of the whole thing. I attempt to re-find the video only to see that it no longer exists.

I have searched EVERYWHERE to find this video and it has either been "Privatized" or completely deleted.

What happened?

I dare not post this on Reddit, and I hope someone can answer my questions.
