Encryption doesn't protect you from being identified. Encryption prevents eavesdropping unto the connection from a third party. DMCA lawyers don't need to do that to identify you as a seeder. All they need to do is request the content from you, watch you send to them, and make a record of your ip address.
The blacklist, maybe protects you. No idea. Though it can easily be circumvented by a motivated group.
Not your keys, not your coins
