I don't know why this should be an issue. I've never posted something to Freestuff but I'm sure there's a form to fill out, just like when we post a message. Why can't there be a checkbox or something that says "PD" for public domain or something like that, to let people know if it's restricted or not? The MarketPlace already has something like this; they have an icon that distinguishes between "for-profit" and "non-profit" purchases. Again, I'm only guessing, but I'm sure there's a checkbox or something that people have to fill out to tell the system if what they're selling is for profit or for charity.
