I actually discovered that Charter has an email for sending abuse complaints. I provided them with a list of all of the subscriptions requests I was aware of that seemed to occur within a timeframe of a couple hours, and I also provided them screen shots of every subscription confirmation or unsubscribe page that showed the IP address from which the original request originated. That was Saturday, I think, and while I haven't received a response, I haven't gotten any more subscription notifications unless you count the Air Force Reserves recruiter who emailed me on Saturday thanking me for my interest in a job with the military.
