There were plenty of people coming from the IPs of music labels on Napster back in the day so it doesn't surprise me that they continue to use P2P services. IIRC, it was on the order of tens of thousands though that included parent companies and subsidiaries. Our lawyers told us it wasn't useful (and might have been harmful) to our case so we never did anything with the information.
