One more tilt at the old windmill. This is not an algorithm; this is a heuristic. An algorithm is (loosely) a method or procedure for achieving some specified end. "... avoid redundancies that could bore the user, like seeing multiple videos with the same music or from the same creator" is the goal, and they have heuristics to try to work towards that, and algorithms and software that implement those heuristics. I think the ship has sailed on this, but when you are in circles where both heuristics and algorithms are in play, this blurring of lines makes for very confusing conversations.
