XanMcC posted a message on a Discord server (Game Trading Server) saying "Can someone please take my steam accoutn off of my hands I honestly don't want it anymore just buy it". I asked if he would accept 60 bundle game keys for the account, to which he agreed. The deal was that I'd initially give him 30, he'd then give me the account credentials and after 15 days I'd send the rest. I sent the first 30 and noticed he was redeeming these keys on the account he had agreed to trade with me, rather than a new account he said he'd created for these games. After challenging him about this, he blocked me on Discord and Steam. I've not heard from him since.
