[Game of Thrones] How does the Night's Watch make its recruits say the words and actually take the Black?

Based on the show, there's a few weeks of training and testing before recruits are assigned jobs and say their oaths.

However, many of them have been sent to the Wall as a punishment or chose it because it seemed the lesser of two evils, rather than going of their own free will like Jon.

So what's to stop them from refusing to swear their oaths and leaving the Wall before becoming men of the Night's Watch?

People who go there involuntarily are facing a criminal penalty otherwise, and drinking bad ale and sneaking off to go whoring in Mole's Town beats a dungeon, or a noose. Refuse to say the words and honor your promise to take the black, and the dungeon or noose are waiting on you.
