Going AFK in the dorms/xenobio/virology/some other rare place shouldn't be the ultimate defense from parapens or other traitor things.  Parapen + C4 will always be a thing as long as ;HELP TATOR KILLING ME VIRO can happen and the chance of someone cloning the body so he can rat you out is there.

Making you be able to track down the ass who stole the hand-teleporter shouldn't factor in paraC4.
