I don't know if it has gotten to that point or not.... I do know that cable companies have been asked in the past to voluntarily supply information on LARGE downloaders. At this time, I don't think that is happening.
Another thing that I have found to have some basis are Govt. Sites..... any .gov site that is federa, imbeds. You can call them Cookies, or Trackers or whatever..... supposedly to help you.... but can be used to track what you are doing on line. Let's say you went on a .gov site for some political info on the Pres, and then you start going to sites that have a lot of anti-Pres dialogue, it is supposed that somewhere a little flag pops up and you are now on a list. You may or maynot be watched a little closer. But seeing that some of our elite politicos in Washington consider ex-servicemen, christians, and practically any conservative of either party a threat to be watched, that these people supposedly have the knowledge and knowhow, have the financial backing, and the God given backbone to stand up for what they believe; you may already be on a list.
Hmmm, I'm on a lot of peoples lists!
