Does anyone know how this works? How do they know that uploaded videos contain content owned or licensed by UMG? Also how do they determine which countries they are blocked in? Here are some examples:-

I uploaded "Fading Away" by Bobby Taylor & The Vancouvers - it's blocked in every country except Saint Martin and South Sudan.

I uploaded "Baby I'm For Real [[The Bells)" by Bobby Taylor & The Vancouvers - it's blocked in Germany and Japan only.

I Uploaded "All For You" by Earl Van Dyke & The Soul Brothers - it's only blocked in Germany.

I uploaded "Whopper Bopper Show Stopper" by Jr Walker and it's not blocked anywhere. It's not even acknowledged as being owned by UMG!

There doesn't seem to be any consistency at all! Who makes the decision or is it just random?
