Sorry to say, most likely a GM will tell you that 'To avoid this in the future...' speech instead of returning the items. Players were warned to be wary of which FCs they joined and what they allowed other FC members access to. It'll most likely be treated the same way as those people who joined FCs shortly after Housing came out, helped donate to the purchase of a house, and then got kicked once the house was purchased. I'm sorry this happened to you. It's why I started a small FC with friends I knew, after leaving a bigger FC run by people I didn't know.
