"If you dueled Shmevin 6 months ago, for $500, lost, and didn't send : we could only ban Shmevin. We could not go into Paypal and like... siphon money from his account."
why would he get banned and not me what, also
"What's been keeping you guys from scamming one another? The threat that if you did, we'd empty out your items? That we'd somehow force the other player to actually send USD on paypal or another system? If that's exclusively why you send your losses to one another after when your duels conclude, then yeah, stop. If you guys continue to trust each other and want to duel for whatever amount USD, go for it."

the only reason why we most likely send is because of the fact that we can get banned along with the consequence that items will be compensated to the other user, if what you're saying in your post is what the rule means now, then basically you are summing it up as to not do usd duels ever again because if you're saying it's not supported but talking about bans and such then what is the point?
