You bought an account (this person an account) from this person 4 years ago, which you somehow know despite the fact that this dude made the user he's selling from a week ago, which means you know the person somehow (let's be real here, you are that person, the grammar similarities between the two are obvious). The funny part is the dude also logged in using one of his previous VPNs because he had no other multiple accounts detected when he posted yesterday, but now it shows one.
He's one more reply away from pulling the classic:
"If you don't stop, I'm going to get my dad! Okay, I warned you.
Hi, it's my, I mean, his dad, you better stop before I call the police! All right, that's it!
THIS IS THE POLICE. We're here to arrest you all for illegal lying and hurting his feelings!"
This is obviously sketchy. User21 sends me a picture of the account that's probably from the first time it was sold to guy above (note the SU3 for master GEO as opposed to how it would now display SU5), then uses the newer picture of the account's current progress after he retook it, likely.
