Someone one young who thinks they are having a laugh or that weird story about the Russian troll farm is one thing.

However actual apparently rational adults doing it what are they getting out of it.
interesting question if it came to light that an actual adult was trolling AH and you were interviewing them for a job would it be concerning or would you think they were just having a laugh.
I am not sure but to me, it would come down on the side of behavior is concerning.
