He's not Bono. We spoke for a while in chat, he seemed a fan, he was talking about GA tickets and ticketbastards, a simple fan going to see a concert, nothing more!
If the real bono is online he can hide his name. By the way, if he really was bono you should not tell in other forums, just for a simple reason, the day someone wrote "bono posted in zootopia", his forum in the site was plenty of crap messages and he hasn't replied anymore!
If you feel to have met bono, enjoy the thing for yourself, cause now next time, 10.000 persons will write to this bono (with the funky b) and you'll never been able to talk with him.
Bye
