"Grabbing/touching people without their consent is harassment," she wrote. "Please do not put your hands on my photographers or friends or anyone you don't know for that matter when you're in the pit at my shows. It's never okay or funny. Thank you. (I can't believe this has to be said...but unfortunately it happens often...thanks for listening.)"
