Why should you be unbanned or unblocked?:I believe I was banned because I logged into my steam account on my friends computer since I wanted to play with my items on my account, and his IP was blacklisted so when I tried to join a server my account became permabanned. This ban happened 2 1/2 years ago so I completely forgot about it as I don't play TF2 much and I didn't realize it would blacklist my steam account since I tried to play on a blacklisted IP.
