It completely depends on whether the accuser appreciates the original gag. No doubt Candid camera had the occasional outtake, maybe someone didn't sign the release at the end, and the footage was lost. If you have a problem with anything on candid camera, you can be accused of being a concern troll. Likewise for naked model photoshoots in public, or dead cat quadracopters. If someone appreciates the stunt, but you don't, then you'll be a called concern troll if you raise any objection.
It's one of the few things David Brin did not predict in Transparent Society
