On the other hand, this is Hacker news, so my first inclination of a response was going to be something like this:

"Get some small amount of bitcoin and pay a VPS hosting provider in Moldova for a year's service on a $15-per-month equivalent KVM VM and put what you know on there anonymously as static content, then publish the link here."

Not that a sufficiently dedicated nation state federal crime agency or intelligence apparatus probably couldn't trace back to you, but it raises the bar for something like random civil lawsuits from piano companies.
