If you lease SP on Minnowbooster or Smartsteem, if then lessor stops using Steem, do you keep delegation until they come back?

Hi guys. So, If i have leased Sp on Minnowbooster, its usually for a fixed term but after that term, the lessor gets a memo from minnowbooster to click on a link to cancel it. Ifnthe lessor no longer uses Steemit or for any other reason doesnt cancel it. Doyou get to keep the delegationtillmhe does or does Minnowbooster cancel it?
