Personally, I don't care if signs are taken away or not. I'm not here to watch the crowd hold up signs that says "Cuck Fena" or stuff like that. Booing, and cheering is something else though. I just think for the most part signs are kinda annoying. Especially when most people diss Cena as a face, and then when or if he ever turns heel than they'll be a supporter. It's a shame!
Signs aren't a big worry oh wow you paid what 2 bucks for a thing of construction paper, and a marker. Big whoop! It could be worse you could be thrown out the building, instead of just having a sign taken away. Look on the bright side of things.
