why did cox disable my internet?

[Larry]

i went on my friends computer to search up why and it says that cox does it for "Infringement" purposes but i don't recall doing anything that would count as being "pirate".
but they wouldn't tell me since my name isn't the account holder's.
So here's what i use internet for:
Anime, Manga, social, gaming, and school work.
i'm guessing that some sites that i watch anime on might be questionable but for even things as low as porn can Cox tell me exactly why they cut off my internet when the account holder calls? because I'm really annoyed
