You were banned for damage mods. There was a report about it a while ago, and since then we've started investigating you. When reviewing the logs we noticed that you only take half damage from every hit that damages you. For example, when someone shoots you with an UZI, you should take 6.6 damage, and you were only taking 3.3. We also noticed that your damage taken would be fine for a part of the game, up until a certain point, at which you presumably toggled it, and from then only started taking half damage anymore.
