Declined Report: 76561198185151223 - ([CSGO] Counter-Strike: Global Offensive Items)

Scam Report

Report Type: [Other] Any other fraudulant behavior
Virtual item type involved: [CSGO] Counter-Strike: Global Offensive Items

Accused profile: 76561198185151223

Victim profile: 76561198038025596

What happened? Description:

We both agreed on the price of 80 CSGO keys for my Stattrak Field-tested M9 Bayonet Night but I miscounted and only selected 60 keys. He accepted, de-added and blocked me after I commented on his profile regarding the loss of keys. I added him after I opened a Reddit GlobalOffensiveTrade post and he added to buy my knife. I don't know what to do and I don't know if there is any chance of me getting my items back.​

Provide Evidence:

I closed the chat window after we traded as I only realized my mistake after I saw "60 new items" instead of 80. I then added him again and he blocked me. Additionally, I also closed the Reddit trade after he agreed. I saw that there is GlobalOffensiveTrade moderators/admins here so if one of them could view my previous posts in some way, they could see my trade and his offer. On his Reddit account linked with his steam, he also changed the URL. I'm also hoping that this can be viewed somehow by the CSGO trade admins/moderators.
I understand there is little/no chance of me getting my items back but I just want this guy marked as a scammer so no one else has to deal with him.
20 keys is around 60 AUD and a big loss for me, I hope something can be done.​
