no you're quite right. Jagex did fail bigtime lol they may as well bring wildy staking and free trade back.
here is the basic idea:
1. player that is purchasing the account/pin or who trading the gold walks into bounty hunter with full sara or sara plate zammy wiz g whatever is agreed on.
2. player who will get the items kills the trader with their expensive items
3. player waits for penalty pick up stuff walks out of Bounty Hunter a lot richer thanks to jagex.
4. player gets his/her account/pin/money for trading off the items
