Swedish YouTube star Felix Arvid Ulf Kjellberg, better known by his online handle PewDiePie, has permanently removed and disabled comments from all his videos.

PewDiePie, who manages the most subscribed YouTube channel in the world, said in a video update that he no longer saw the value in user comments as they were plagued by spam and arguments.

"I don't mean to offend you bros who show me support, but I don't see that same type of support anymore," he said.

"I know I complain about the comments a lot, but it's my main way to communicate with you bros. I go to the comments and it's mainly spam. It's people self-advertising. It's people who are trying to provoke.

"It's all this stuff that to me doesn't mean anything. I don't care about it. I don't want to see it. It's been bothering me for so long now. I've been trying to find solutions to it, and trying to find ways to make it better, and I'm just sick of it, so I'm going to turn the comments off forever. "

I go to the comments and it's mainly spam. It's people self-advertising.

PewDiePie said he hopes his subscribers understand his decision, and pointed out that he would be communicating via Twitter and Reddit henceforth.

The announcement comes as the internet celebrity announced that more than 30 million people have subscribed to his channel.

PewDiePie has gained tremendous popularity over the past several years by publishing various Let's Play videos online. Publishers and developers are beginning to note the commercial impact of his videos, with games featured on his channel often climbing in sales.

Skate 3, for example, has remained in the UK top 40 chart all year despite being released in 2010, primarily because PewDiePie continues to publish videos of the game. Publisher Electronic Arts decided to capitalise on this deal by printing more copies of the game.

The polemical mobile game Flappy Bird, meanwhile, became an overnight sensation after being featured on PewDiePie's channel.
