Apparent suicide at Burning Man. "Friends thought he was doing an art piece"

I really really want to believe not all the facts or the complete story is being told here, and I'd like to believe being up there hanging for two hours is due to previous experiences with him hanging around his art piece, and not just because everyone was drugged off their gourd. But every time I try to give humans the benefit of the doubt, I get re-impressed with humans' abilities to go to new lows.
