Moisture Farmer

ASK FANTASY FLIGHT 

Q: If you use the reaction on Questionable Contacts and then have a Moisture Farmer take the damage instead of the objective (due to "Protect Tatooine"), is the cost still considered paid and you may then move 1 damage from a target friendly unit to a target enemy unit?

A: Yes. Protect only changes where the damage token is placed, so if you are protecting a card that is being damaged to pay a cost, the cost is still paid.
