You have 3 accounts that have registered to your IP. One which was banned from our server for LMAObox spam, which now has a VAC ban on it. You then rejoined our servers with your main account an received a ban because the throwaway had been banned.
It seems that a player
Lavawolf12 joined using your IP and received another duplicate account ban, though this seems mistaken as this appears to be an entirely different person.
While your original account ban has been lifted, the other player who joined reset the duplicate ban.
Does this throwaway account ring a bell?
