Agadmator runs an extremely popular chess-only youtube channel / subscription and it has been on with no problems for YEARS. He has a deffinite accent so I think he is of (a guess) slavic ancestry but speaks fluent English. Has done thousands(?) of game analysis for eras from Paul Morphy to current world Grand Master Magnus Carlsen. He was doing an interactive podcast when he got blocked by Youtube about an hour in. An immediate protest was almost immediately denied. Most likely an algorithm / bot, but an increasingly obvious hyper-sensitive Youtube habit.
