Idea for spy: Informants and double agents

[Roomba]

Why would anyone want to be an informant? You spawn at the neck and call of another player, with your role overwhelmingly relegated to the grunt work of grabbing stuff and transporting it from one place to another. In return you get none of the fancy toys your master gets as a reward for your work, none of the antag license to be as murdery as you want, and the liability of being adminhelped if your master deems you insufficiently helpful. And since the informants know their master's identities, all it takes is one informant disgruntled with this arrangement to ruin their master's day at roundstart.
