There's got to be something more to it, surely? It's really unfair and practically impossible, hence the name.

A) He is wearing a mole costume with a sign saying 'I am a mole'
B) Any sabotages that happen they are automatically going to assume it's him responsible
C) If his task finishes today and there's meant to be an eviction, wouldn't it be live?
D) They are going to ask the housemates who they think the mole is - couldn't really get much unfairer.

I really don't see why they'd waste their time on a task so unfair and to which the outcome was pretty obvious from the start...there's got to be something more to it.
