trade char through sell on website

I am wondering a couple things about this
1. If i was to say i wanted to trade my paladin for a warrior. But i would sell my paladin to someone i have set it up with, then turn around and buy his warrior right out so only warmane takes out his and the buyer gets his coins back only the two toons traded, would that still be bannable?
2. Would anyone be willing to try this or is it just a fart in my head again.

Let me try to explain better.
Tom has a 6k warrior, Bill had a 6k paladin. They want to trade but use the selling system on the website. So Tom puts his paladin up for 500 coins. Bill buys it. With the coins that Tom just gained, he buys Toms warrior for a even trade but a sell on both ways, would that be allowed? I would think you would have to find someone to do it so chat in game about it for a few or something. But idk if the GM's would allow just wondering and blab coming out of my head here.

On a last note, Turtles. That is all.

Still looking for answer to this guys

Why wouldn't that be allowed? It's just a clever usage of website mechanics.

On the other hand you have to be sure that guy wont keep the 500 (speculating the amount of coins). But still you have to purchase 500 coins yourself (or what ever amount you like) and with that coins you can probably gear your own warrior and keep the paladin.

@ #1. No. Not bannable.
@ #2 Arrange that in-game out somewhere else away from the forum, please.
