it's so the fans behind them don't have to stand the whole game? I really appreciated that.

Although we had two kids directly in front of us, one with crutches, and they tied shirts onto the crutches and held them up right at eye level. I was nice about it, but I let them know they could do that whenever they wanted, except when they were playing. Had to physically push them down a few times. I don't understand people who feel the need to lift up signs or crap. Nobody can see them and nobody cares.
