Electronic Frontier Foundation (EFF) released a step by step guide to figure out if your ISP is logging your internet activity. Due to the recent complains by many Comcast users that their online activity is abruptly cut-off because of their heavy use of torrent downloading.

EFF, with the help of whireshark shows you how to verify if your ISP is doing the same to you in your region. They also released a python-based tool to compare packet captures and determine if they are potentiall “forged, dropped, or mangled packets”
