They do suck. One time they playeds a round, where they named themselves stuff like, marshmelow, jony dep, and crap like that. They took all genetics equipment, I tried to stop them, but they gibbed me, then as a ghost I watched what the did. In assistant storage, they took all the computers from the station, all security equipment, (they deleted walls and doors to accomplish their goals too.) They took other stuff too, like the Ai modules, they made the captain drop everything then gibbed him.
If that wasn't grief then I don't know what is.
