What prevents miners in a pool from retaining the reward?

Question

From what I understand miners submit their hashes to the pool. What prevents a miner to disengage the pool as soon as she finds the right hash?

Answer 1

The payout address for the miners mined blocks is the pool's moderator address. If the miners are working on blocks with a different payout address (ex. their own), the pool moderator can tell and act accordingly by either banning them or simply ignoring their work.
