Anyone can hire a debt collection firm for any reason at any time. The only thing ebay can't do is harm your credit report since the don't have a ssn or anything to harm your credit with. They can file a civil suit against you in court and obtain a judgement however who are they going to serve a judgement on if you don't exist.
