YouTube's war with ad blockers is far from over, and it's focusing on tools that enable ad-free viewing on mobile this time. The Google-owned video platform has announced that it's "strengthening [its] enforcement on third-party apps that violate" its Terms of Service, "specifically ad-blocking apps." It's talking about mobile applications you can use to access videos without being interrupted by advertisements. When you use an application like that, you may experience buffering issues or see an error message that says "The following content is not available on this app."

The service says its terms don't allow third-party apps to switch off ads "because that prevents the creator from being rewarded for viewership." Like it's been doing over the past few months since it started cracking down on ad blockers, YouTube suggests signing up for a Premium membership if you want to watch ad-free. YouTube Premium will set you back $14 a month. 

Back in November, YouTube told us that it "launched a global effort to urge viewers with ad blockers enabled to allow ads on YouTube or try YouTube Premium for an ad free experience." It started by showing pop-ups whenever an ad blocker is in use telling you that it's against the website's TOS. Soon after that, you could only play up to three videos with an ad blocker on before you can no longer load any. Google also later admitted that if you have an ad blocker installed, you "may experience suboptimal viewing," such as having to wait a longer period before a video loads.
