When you're learning to play a musical instrument, you have to play the same songs and scales over and over again. YouTube's algorithm doesn't seem to know this, and so it demonetized a piano tutorial channel for "Repetitious content."
We just found out that our channel was demonetised for "Repetitious content" and we believe that this is an error, possibly decided by an algorithm, and now the biggest part of our livelihood has been taken away. Please help us by discussing this (tweeting and posting) if possible. We need to be heard by YouTube. It's a risk for the piano and synthesia community as we all have similar-looking videos.
I hope they get this sorted out soon!
