I witnessed this first hand. I was praising exo when all of a sudden an ELF grabbed me and started saying extremely rude and inappropriate things. He touched me in places he should not have and threatened to cut my throat unless I bought Super Junior's album. It was a frightening experience. I hope no one else goes through this...we have to put a stop to those creatures . And I felt violated after watching the Sexy, Free & Single music video...my eyes could not endure the pain.
