IKEA furniture loophole. They’d basically have giant recalls of pieces of furniture and would pay out large amounts of money ($600+ a dresser) for finding them and taking them back to IKEA to be destroyed

Edit: the loophole is that because I’m a minor they have no way of recording how many pieces of furniture I’ve recalled for them. If you have your license they can mark your info each time when you do it, but because I didn’t they couldn’t record it. You were supposed to be able to only do it 3 times each person.
