[2021] Trade dupe exploit still works

It does not look like the dupe actually exists in the way folks are reporting, but to be sure, none of you should attempt using this because even an attempt, once it hits our exploit threshold, will trigger a suspension/ban.

I am closing this thread since it has a response to the original query from a developer and is starting to spiral off-topic. If someone has an exploit to report with clear reproduction steps, please feel free to dm them to me in the interim.
