Yes! I taught my younger "cousins" - not my kids - horrible lessons that day! I broke every rule in sight, disobeyed all authority, knocked down all the nearby kids in the area to guarantee my cousins would be selected, even slipped the Jedi CM a $20 so they could get special treatment afterward and get autographs. Then bought our group rounds of beer at Glowfest to celebrate our piracy and defeat of the Disney rules and regulations

.
Of course we weren't going to give up so easily! There was absolutely no way we were going to waste time going all the way back to the Mickey and Friends parking structure to drop off signs we had used several times in the past without any issue from security or insight that there were even policies - for all we knew we may have just had a picky checker who has a grudge against JTA since she use to work it, and of course the supervisor wasn't going to disagree with her ruling. The checker's issue wasn't the fact that I had signs in general, it was the fact that I used posterboard. Had the signs been made with standard 8.5 x 11 paper then based on what the security CM told me herself there would not have been an issue at all. So yes, after learning that info we did knowingly and willingly disobey the checker and snuck them in, I would have put them down my pants if it meant getting them past security that day.
It's very difficult for me to believe that no other party would have tried going through a different checkpoint, there's no way anyone would have been so willing to walk back to the tram, travel back to the parking structure, walk to the car, drop things off, walk back to the tram, travel back to downtown Disney, and back through security again - complete waste of time.
As for teaching the kids lessons on how to cheat the man, I'm not even sure they're aware of what happened. Were we nervous at the show when we didn't see others with signs?, more confused than anything since this was the very first time we had not seen other signs but yes and we almost didn't use them. But we ended up getting spots in back so we decided to use the signs so the kids could stand a chance. I didn't sneak in my own booze or drugs, or a weapon to shank Mickey, I snuck in harmless signs to help my cousins increase their chances of being selected. If anyone wants to accuse us of teaching them life altering lessons that will result in them growing up to con and break rules because we decided to sneak in signs that we had used many times before and never considered them to be contraband until that day, then fine I'll take it

. They and we had a very memorable experience and outcome that will most likely never happen again or happens to very few. Am I proud that I decided to go against this "new to me" policy and sneak them in?, based on the outcome yes I think I am but "now" I'm aware that there's a sign criteria so I will need to make new signs that will continue to disappoint others in the crowds who do not have signs. I have florescent standard paper that will work, not as cool as posterboard but supposedly within regulation.
The CMs working the Jedi Training Academy do have a mind of their own and are very well organized, they're not solely relying on security to deny signs. They were walking next to us most of the time and did see the signs long before the show started, they could have easily said something to us before and afterward but did not. They were pretty good about telling people to park their strollers elsewhere and keep their kids behind the blue line so had they felt our signs would cause harm or be a distraction I'm fairly certain they would have said something to us.
