About "Ado's Box"

Hi!

Someone has seen some live from Ado in which Ado's Box was deactivated for violating the rule of no phones, no binoculars and cameras?

I'm curious because i'm afraid of paying the Hibana ticket in Barcelona and not being able to see Ado for some jerk that uses the phone or something...Do you know if they are strict about this?

Thanks!!
