Famous YouTube personality Felix Kjellberg, aka PewDiePie, pulled off one of 2016's biggest pranks online by promising to delete his famous YouTube channel after reaching 50 million subscribers.

At the ultimatum set by PewDiePie, which was last Dec. 10, at 12 p.m. EST, his channel reached over 50 million. To be fair, the famous YouTube vlogger did fulfill his promise. But he got the last laugh as it turned out he was actually referring to his other YouTube channel and not the one that just gained more than 50 million subscribers.

PewDiePie's promise to delete his channel came after explaining how YouTube algorithm changes affect small and big names of producers in the video streaming platform.

In a video posted earlier this December titled "DELETING MY CHANNEL AT 50 MILLION," PewDiePie explained the huge effect of YouTube's move in changing the Subscriptions feed with the Recommended and Suggested videos feed.

As he explained in the same video, once a YouTube user opens the platform, the first tabs that will appear are the Recommended and Suggested feeds and these contain videos from various YouTube uploaders, even the ones who the users have not subscribed to. On the other hand, the recent uploads from YouTube video producers to whom users have subscribed to is tucked in another tab that PewDiePie says "no one clicks."

PewDiePie added that YouTube is automatically unsubscribing YouTube users from channels regardless of how frequent they visit it. He showed as example that he was mysteriously unsubscribed from a channel that he always checks out while he remained subscribed to channel that he has not visited for a long time.

What disappoints PewDiePie more is how YouTube responds to complaints regarding the matters that he raised. Reports mentioned that a lot of other YouTube video producers have been complaining about the same matters.

Just last week, a Google representative handed out a statement about the matter to Ars Technica and said: "Some creators have expressed concerns around a drop in their subscriber numbers. We've done an extensive review and found there have been no decreases in creators subscriber numbers beyond what normally happens when viewers either unsubscribe from a creator's channel or when YouTube removes spammed subscribers. We do the latter to ensure that all creator subscriber numbers are accurate."
