An MJ 팬 club is on a desperate mission to clean up the recent graffiti onslaught outside the King of Pop's tomb -- claiming a few bad apples could spoil everything for MJ's non-vandal followers.
The Official Michael Jackson 팬 of Southern California have extended an 올리브 branch to Forest Lawn Cemetery -- where MJ is buried -- offering to clean up the recent wave of hidden vandalism outside the singer's tomb ... before the cemetery decides to ban MJ 팬 altogether.
A rep for the group -- which organizes a monthly pilgrimage to MJ's burial place -- tells TMZ, they want to "fix this mess" so FLC doesn't associate MJ's upstanding 팬 with a bunch of sharpie-wielding hoodlums.
As TMZ first reported, Forest Lawn is currently on red alert over the illegal doodles -- hunting down the artists responsible ... and threatening to ban any potential copycats for life.
No word if Forest Lawn will take the 팬 group up on their offer.
