Yeah, that would irritate me, too. Years ago I had people mess with my games and then I replaced the locks, that problem solved. Now i just have to deal with typical abuse and some asshole that likes to spin up the front leg levelers on some of my games. My games are not too steep, so spinning up the levelers messes up gameplay and I have to take the time to readjust everything and lock them in. If I see it happen again, I will make time to sit through a weeks worth of camera footage to nail the guy.
