We guess you could call our reaction to the pictures of Justin Bieber apparently smoking a joint extreme. If you call letting out a 'tsk' sound that our mother would be proud of and furiously shaking our head extreme. But the online reaction has been so EXTREME, we had to capitalise it.

Prompted by users of website 4chan, Beliebers were encouraged to take to Twitter and post pictures of themselves self-harming with the hashtag 'CutForBieber', to demonstrate how upset they were about the pictures.

The campaign was started by some terrible internet trolls on 4chan, a site that hosts a number of bulletin boards where members can post pretty much anything they like.

On a board that has now been removed, one user wrote: 'Lets start a cut yourself for Bieber campaign. Tweet a bunch of pics of people cutting themselves and claim we did it because Bieber was smoking weed.'

Whilst some Twitter users found the #CutForBieber hashtag amusing, it made others more than a little angry.

The most high profile tweeter to react to the sick campaign was Miley Cyrus, who retweeted: '#cutforbieber? Cutting is NOT something to joke about. There are people who are actually suffering from self-harm, this is so disrespectful.'

Following the publication of the controversial images, Justin himself took to Twitter to write a series of emotional tweets, with the singer revealing that he was ‘growing’, ‘learning’ and didn’t want to ‘let any of you down’.

He said: ‘Everyday growing and learning. Trying to be better. U get knocked down, u get up.

‘I see all of u. I hear all of u. I never want to let any of you down. I love u.’

Justin continued: ‘Like i said...2013...new challenges. new doubters... I’m ready. We are ready. see u all tomorrow and everyday after that.’
