You can change email/password to your own. Username is already set though and a few games have been played. Trying to sell quick and cheap through middleman on site.
No. In fact, somebody DM'd me and I was dumb enough to try and buy an account through Discord. Marlboro5 just scammed me and I assume has already scammed countless others. He will link you to a "reputable" steam account and trick you into thinking he is a long time trader/middleman. Right after you send payment he will block you. Do not attempt to trade in Discord or email. You will most likely get scammed. There is a chance this posting was also made by the scammer in order to bait willing buyers into an off-site deal.
