Name in Game: Absolution
Steam-ID: STEAM_0:1:12425358
Who banned you: sup
When:yesterday
Where: web ban
Why banned: "sabotage"
Link to ban: http://www.ibisgaming.com/sourcebans....php?p=banlist


I have no idea why im banned. I wasnt online when this happened so i dont know what "sabotage" i could have done while i was away from my computer. It says "web ban" by "sup" so idk what web ban is and idk who sup is either.

Im guessing this was a mistake, could i be unbanned please.

Whatever this is for, 2 day ban for a first time seems too much. Could have been a couple hours like most of the bans i see on the ban list.
