I've DNT'd him for now as a precaution while I await @Wortel (or you) to post the rest of the story here. Please get back to me as soon as you can on this, thanks.
Explanation of the trade: Seems like he was cutting @T1N0's buy price (which was 0.74/m) and @Kigis claimed to buy it for 0.88/m. Seems like he scammed around 135M 07GP. Kigis later on kicked the guy from the Elite Ranks Discord server.
How they scammed: Did not pay out via PayPal after and banned the user off Elite Ranks's Discord server.
