YouTube is conducting a “small experiment globally” warning users to turn off ad blocking to avoid being limited to watching only three videos. This is reported by BleepingComputer.

YouTube now displays a pop-up warning ad blockers that “video player will be blocked after 3 videos”.

“It looks like you may be using an ad blocker. Video playback will be blocked unless YouTube is allowlisted or the ad blocker is disabled,” the message adds.

It reminded that advertising allows YouTube to remain free for billions of users around the world. So users can upgrade to YouTube Premium without ads, and creators will still get paid for the subscription.

After receiving this message, users will be able to turn off their ad blocker or subscribe to YouTube Premium and get rid of ads altogether.

“We’re running a small experiment globally that urges viewers with ad blockers enabled to allow ads on YouTube or try YouTube Premium,” the company said.

It also said that in extreme cases where viewers continue to use ad blockers, playback will be temporarily disabled.

We will remind that in May YouTube asked some users to turn off ad blockers or pay for a premium subscription, otherwise they will not be allowed to watch the video.
