As I know if you choose 10 days payout option, you must leave the campaign afterward.
If you still want to change your mind later on, you can do so by 10th of Dec. The first payout goes out on 11th and I can pay you at the same time.
I will actually make it general. Anyone can take the pay for the first 10 days (as outlined in the 10 day payout scheme) and leave.
AFAIK, it mentions that, if the user wants he can leave the campaign after the week.

Note:- Re-enrollment after each 10 days is automatic, no need to post again.
- Re-enrollment may be refused after every 10 days.
