What is a Middleman?

[Dufuox]

Title. What do they actually do? Do they supervise account trades, or what?

 

[Lillie_Services]

They are there to supervise any type of trades.

You might want to refer to one of those following links, which will introduce you to Sythe.org

Wrong section by the way... :/

You give the middleman your things, the person your trading gives them their things.
The MM checks if anything is wrong with the items and gives your stuff to the other guy and the other guys stuff to you.

Thats all I know.
