There is a current email phishing scam going on where you get an official-looking email forwarded by your ISP, which states you have violated HBO copyrights and illegally downloaded Game of Thrones.
The email has a link to a website where they say you can pay the fine. Don’t fall for it. The message was sent by cybercriminals and they would get any money you pay.
In general, it’s a bad idea to illegally download shows and movies for two reasons. First, you are indeed violating copyrights which can turn out to be very expensive when you get sued. Second, the websites promising these downloads are often compromised and infect your computer with all kinds of malware.
