I have evidence!
This is more than likely by Plastic (Makers of Linger in Shadow)
As I stated earlier the original uploader is in Poland, as is Plastic.
Looking through the old videos I managed to find a brief glimpse of the YouTuber PLmae
Now, he looks a lot like Paweł Czubiński from Plastic, and his nickname is mae
PL meaning P
and and mae
being his nickname aka PLmae
Coincidence... I think not! =P
