Blocking a person on Spotify is not the most popular function on the music streaming site, but it is feasible to do so whenever someone has nagged you too much.

To block an individual:Go his Spotify profile Choose the “More settings” option, which is represented by three little dots Then tap on the “Block” button.

If you change your mind, the process can be reversed at any time. However the best thing is that a  blocked user will be unable to access your profile, listen to your music, or browse your public playlists. Source: Engadget
