I'm not suggesting a listing fee or anything like that, like the auction house has. That's not my concern. My concern is the number of offers that are probably from unused accounts, or will be. I'm guessing there's a new surge in players due to quarantining? That's at least why I'm here, and it means a load of people are going to be out once quarantine is over. And if they're like me, they probably have 40 offers on either side of the market, and will not bother taking these orders down once they stop signing in. Letting these stay up might result in a largely fraudulent market for a while, where legitimate players have to compete with dead accounts that have nothing to gain and nothing to lose. That probably shouldn't be allowed to happen. A simple fix would be to knock out the offers of people who haven't logged in for thirty days.
