Michael Jackson's death has left fans so devastated that several have committed suicide, according to the man behind his biggest fan site.

Gary Taylor, president and owner of MJJcommunity.com, believes 12 people have taken their lives in response to their idol's death.

A worried Jesse Jackson has issued a YouTube message urging fans not to "self-destruct".

"This is a time when hearts are heavy," says Rev Jackson. "There is great pain but great cause to celebrate Michael's life.

"It made Michael happy saying 'We Are The World'. Don't self destruct.

"We fall down sometimes, we get back up. That's the right thing to do. In Michael's name let's live together as brothers and sisters and not die apart as fools."

Taylor, whose online community has more than 14,000 users and 30 staff worldwide, echoed the reverend's words that the singer would have been devastated by fans' deaths.

"I know there has been an increase, I now believe the figure is 12," he told Sky News online.

"It is a serious situation that these people are going through but Michael Jackson would never want this. He would want them to live."

The London-based entrepreneur said he was also having trouble coming to terms with the loss.

"I'm stunned that he's dead. One minute he is coming here for concerts and the next he is gone."
