There are a few sites that allow items/currency to be changed sites. Wajwas was another, think I got the name right. I know Neopets, Subeta and Gaia frown on it but people do still swap the currency for other currency on 'black market' sites. Than again, Aywas you can buy and sell accounts as well, only game I know where account buying is allowed.

Some sites don't allow it cause the art, etc is copyrighted to them and you making money off their property is frowned at, real life or pixel money. Yet, I know people have said if Neo offered a way to buy UCs or turn pets UC, they would spend the money to do it which would be better for Neo than trying to track down black market accounts, etc.
