I have recently unable to come in contact with tf2 op staff regarding the fact that I was banned for "being an alt", which is clearly untrue!

A few days ago I logged onto outpost saying I was perma banned because I was an alternate account of another outpost user, his profile page I was unable to view due to my ban. I filed an appeal stating I was confused about what was happening and I didn't have any alts. However, the admin replied saying I was "clearly" a alt of another user, which he sent the steam profile link of: https://steamhost.cn/steamcommunity_com/id/JoeyCahill/. This user lives in Australia. I live in China! I was greatly confused. The admin might have thought I was an alt due to the fact that I am f2p and my items are gifted from my friends. I pondered a bit and realized that I have accesed Outpost using my VPN service. I believe that is why my account may be flagged as an alt of another. Different VPN accounts and users go through the same VPN server. The admin closed my appeal and I was unable to communicate further to explain. The admin's name is toughsox and I hope through this I can communicate with some admins and fellow outpost users.
