TWC or RR is TWC doing this in their markets or is RoadRunner doing it? Their is a big difference between the two companies. TWC is the actual Cable Operator who can set up their own polices. RR is the actual ISP who also who sets up their own policies- like TWC will tell you that they don't do anything to P2P traffic but RoadRunner will tell you different and is actually stated in the RoadRunner TOS and AUP on the RR site.
DSLReports should find out which company is doing it instead of saying both of them are when it came from an "insider" at TWC.
