To help avoid being traced, you'd need to fully anonymize your credentials, especially your payment method - the account where the money will be deposited (from the buyer) upon sale.

Never actually considered this but i feel like there would need to be a police level investigation for them to dig that deep.

Not necessarily.

If the transaction demonstrates you're the original buyer who sold an Item that's supposed to be non-existent (and the company has knowledge of It), then they can take further action - without police Intervention.
