My ISP will send letters or emails, but only if they get a complaint from the company in question. Usually what ends up happening is a company watches a torrent, and takes down a list of all the ip addresses downloading it. They then send boilerplate complaints to the isps associated with said ip addresses, who are legally required to do something about it. My little brother got in trouble this way lmao, they sent a letter to our house about it.
