I was throwing out a nuclear option showing that there are options. This is valve where best of the best work here, and implementing locked down trading can work to thr point they cut out the external trades or make it so hard to move the trade of thr platform that it would effectively kill the casino portion. Albeit this would hurt their earnings.

Tbh valve could stop this by making it only tradeble to your friends or make the skins non tradable so they are just that, skins for you.
