Ad-blockers may clear up websites full of spam but when it comes to legitimate services like Spotify they’re hurting artists and industries. Spotify aren’t going to take it anymore.

In an update to their Terms of Service Spotify have made it clear that they are taking ad-blocking on their platform seriously. The new rules state that “circumventing or blocking advertisements in the Spotify Service, or creating or distributing tools designed to block advertisements in the Spotify Service” will result in a suspension or total termination of accounts.

Spotify offer 2 different tiers for unlimited music streaming on their massively popular platform. You can pay a subscription charge or you can listen for free with adverts interspersed between your music. But for some apparently almost the entire catalogue of music in the world for free isn’t enough and they need to block ads – essentially killing any profit for the Spotify team and most importantly the artists and labels.

Spotify have measures in place to limit users ad-blocking on their service but now they are taking it more seriously with long-term repercussions for offenders. A spokesperson said that they have “multiple detection measures in place monitoring consumption on the service to detect, investigate and deal with [artificial manipulation of streaming activity].”

Last March it was reported that around 2 million users, roughly 2% of their free listeners, were using modded apps and accounts to get around advertisements. At the time Spotify began disabling accounts when they detected abnormal activity and giving users a chance to reactivate their accounts after relinquishing the ad-blocking softwares. Now they are being less forgiving.

Their new Terms of Service will allow them to terminate an account without warning and will go into effect on the 1st of March.
