Say you publish something you REALLY worked hard on in the invention store. Maybe have an option to set a price range of 1-100 or 1-??? tokens to download. So when someone downloads your invention you can get paid.
(But with a system that like, if its a scam you can refund it by deleting it and it also removes that item from everywhere you spawned it at.)
(Or option to report the scam, and only if the item is proven to be a scam, then you get the refund, to avoid false refunds)
