Agree. 3dxGold farming could become a real thing in our little sex game. It happens with most innocent free-to-play games. 'Warframe' for example... probably one of the most honest and well-run free games out there. But if you go into the trade chat it's a different story. In-game currency being swapped and sold for whatever as if the game has switched from space ninjas to Wall Street brokers.
My point is: this will change the way people play and our not-so-innocent game could become ugly. There might be a lot of members that will just use the trade as another form of gift for their lovers or friends, which is of sort of nice. but then, there will be others that will create some kind of market. Either by making a Brothel where you pay per lay or something more insidious like creating troll rooms by placing pay items all over the place or in usual walkways in an attempt to trick an uncareful clicker into purchasing a 'mini pose' they didn't expect. Or heck someone just asking for 3dxcoin for a bit of fun, then blocking as soon as they receive.
Quoting Stronos:
"Do you realize so fare we have been already paying a subscription for a game that, if gets 2 major updates a year, it is already a miracle?"
-We're already paying for the game. As awesome as the updates and additions are- They're really not a free service.
