Request for unbanning main

Hey, my main account is Spraaaaty
I did a trade with another user and used Shadow as a middleman. The trade was $40 codes I believe for a CSGO knife, it went smoothly, then the guy wanted to sell another knife for me and he sent it first and I just left, I'm not really sure why I did what I did, but obviously Shadow rightly so proceeded to perm ban me. Miss the forum and want to return, been like 2 years since the ban and am willing to pay the full amount back to the initial victim. Hopefully we can resolve something. The trades / transactions took place over Skype, and since I have a new computer I don't have the old Skype logs, I've reached out to Shadow on Skype in hopes that we can help me find the person I need to re-imburse. I can't check my steam trade logs because I sold the account a while ago. I will try my best to find the person though, it may be possible that I PM'd him from the account if maybe staff could check the PM's on that account, otherwise I will host a giveaway if I am allowed, the knife's value was roughly $40. Thanks in advance!
