A side business of my sister relies heavily on FBM (furniture flipping - find free furniture, invest a few hours and dollars into them, and list them). To date nothing weird like that has ever happened. Sometimes the post get 0 views, but never been deleted. Mattresses have a bit of a gray area. Depending on the state (yours or facebooks, could be either or both), you might not be allowed to sell a used mattress.
