Server Dupe

Hey guys, so i've been searching a server with a population of about 90 active players for duping methods. I've managed to find a way where i can close my trading interface on one account and use all the tabs above and bellow the inventory. Only issue is whenever i teleport it closes the trade. I can open up GE, use emotes, use prayers while in the closed trade interface but cant request another trade, move, or challenge at duel arena. Any suggestions on what i could try next? I'll leak the server and the method up to this point to the person who can suggest to me an idea that works.
Thank you

I think that might ascutally work on not just runscape; i tried it on animal jam and it worked great!

Try poisoning yourself and getting to the trade window you want right before you're about to die?

Mind sharing this method inbox so I can try it?

Hello, curious about how it went. Any info to share?
