Kinda pointless for anyone easy to spot/tell being undercover.

There is likely to be people in Hollywood working with and for the good guys of their own volition, it is however unlikely to be anyone that are vocal or obvious, might be someone that is low-key acting like they are in line with the Hollywood party line and it might even be someone that are vocal and loud about towing the party line.

Anyone that we might suspect is unlikely to be with the whitehats in anything beyond a perfunctory capacity unless they have gone completely of the radar.....
