Live performers have been receiving a lot of attention lately for all the wrong reasons.
Case 1. Enrique serenades another man.
Case 2. Akon throws person into crowd
In a live performance someone throws a bottle at Akon, he gets the person on stage and then dangerously throws them back into the crowd.
You are not just performing to the visible audience in front of you but also a larger secondary audience. Where Enrique I am assuming was playing in a gay club and that behaviour would have been looked at in a favourable light. In the harsh reality of Youtube the response has not been so complementary. Same with the case for Akon
