Why do I get an email for a banned playlist for software tutorials - also Its been up for a least 6 months.

I am trying to understand how and why a playlist I made for my self is being banned for some inapropriate reason. It is just a playlist for tutorials for some audio software. I just got this mail from YT.

Any thoughts on this BS?
