Apparently the reasoning behind this is that I used "misleading titles / thumbnails" - Which makes no sense, as every thumbnail and title I use, relates to what's in the video, no matter how mysterious. Waiting for a reply @TeamYoutube to rectify this so I can get back to work.
This is just insane. But sadly, I knew it was coming sooner or later. They need to quit silencing people, and when asked why come up with some stupid explanation. So ridiculous.
