Are you like a pro-pirate or something? If you don't do anything wrong nothing will happen. If you pirated in the past that won't count. What counts is the stuff you do after they establish it on your ISP.
well i download youtube videos and images a lot i don't know if any of them are copyrighted
Your ISP has no way of knowing you downloaded a YouTube video since it gets the file from the same URL used to stream it.Same with images. Displaying it on a webpage is the same as saving it.
What the forget is this bull stuff?"Tamper" my internet speeds and make me watch an educational video?
How the hell else would somebody use your internet? You either let them, or you didn't have decent security on your wifi.Both things would be at least partially your fault.
