Using illegal sites and file-sharing programs can be risky,
Using illegal file sharing programs exposes users to the risk of unwelcome content such as viruses, violent images, and explicit content.

You could be breaking the law and face consequences,
Copyright law applies to downloading, sharing, and streaming just like the real world of physical CDs and DVDs. If you make music, film, or TV content available to others on a file-sharing network, download from an illegal site or sell copies without the permission of those who own the copyright, then you could face serious penalties. 

Using legal sites rewards creators for their work,
Copyright laws protect those who work in the creative industries and allows them to be rewarded fairly and to continue to create the music, film, and TV programs we all enjoy so much.
