Keeping torrents anonymous?

Ok. so u use utorrent and kat.ph to download everything thing i need or want (programs, music, movies, ect) well i taught my friend how to use it all so. Well ive used it way more than him i talking $1000s worth of stuff ive downloaded. He doesnt download that much but he got a warning and got his internet blocked until he filled out a few of those "i agree" pages. any way i can avoid that from happening to me while still using utorrent? anyway of blocking my ISP from seeing it?
