TL;DR: for a whole decade YouTube allowed a copyright troll to claim all the rights on a recording of a washing machine end cycle chime
The account of the copyright troll is still standing and it’s not permanently banned
IMHO in this case YouTube should permanently ban at the first offense any copyright troll that maliciously claim as their property something that’s in the public domain
Also: if it wasn’t that it affected a big streamer with lots of followers, YouTube would have ignored the problem
What they should do is properly DMCA - then the copyright trolls would be out an extensive amount of money, but no they’ll keep on using this completely broke system because the billion dollar major licensing companies aren’t negatively affected by any of it.
