Well..This actually depends on some factors.. Example:Some people that create torrents just usually dont put any link related to the website where it was downloaded or to advertise,But this is PURERLY optional,.If you want you can put the link in the folder of the torrent and if the user doesnt enter the link then they cant use the folder ( just a example).So it wouldnt be such a bad idea to use it as advertising,thats really good to point out
