I just watch the games on TV, so I don't know how closely those seats are monitored by security and how often they approach people asking to see their tickets.
In my experience the only seats closely monitored are the lower bowl on the bench side. You must present your ticket each and every time you attempt to enter. I never sit in lower bowl unless I'm given the tickets - it's more fun and a better view in the upper bowl.
