A friend got his own cease and desist letter the other day. His ISP forwarded the notice from a copyright enforcement agency along with five pages of content intended both to stop those that know they’re sharing and help out parents (or others) who may not be aware of what all is going on with the computers attached to their cable modem.
Of course you’re a valued customer, and of course it wasn’t your fault, just stop it is the message.
It’s nothing like the major raid that shutdown a big piece of the eDonkey network this week, but it’s apparently scary enough.
