I wonder how much putting a CDN in front of this would reduce this.
According to the readme, it seems like the bulk
of the traffic is highly cacheable, so presumably you could park something a CDN in front and substantially reduce the bandwidth requirements.
I would agree completely. There are documented instances of this entity being called out by the parties who actually own the rights to the music. I described them as fraudulent for a reason: what they are doing is fraud.
Ingroove is known to be a fraudulent troll. They have been doing this to massive amount of creators, in many cases asserting rights to music they do not own the rights to.
