I wonder if they ended up giving all their private information:
> So that the complaining party can get back to you, please provide both your telephone number and physical address.

And if they did, then it would be interesting to see if MPA ended up going after them. If I were youtube-dl then that would be the only thing that might stop me from writing a counter-notice.
