Welcome to the forums, xl0rd!
Thank you for the kind words and compliments. GC is one of the last bastions for fun, friendly, and cooperative L4D2 gaming. Regarding your ban, you used a graphical bug or glitch of some type to get up to that area. We don't condone exploits of any bugs and/or glitches to gain any unfair advantages on our servers, or inadvertently give the infected team unnecessary points. It can possibly get you killed because one can help you. Remember that this is a modded points server, and you dying from full health can gain an infected at least half of the points required to buy a tank, or earn a potential tank enough points to buy a heal. This is the difference between all survivors making it to helicopter or only a few or none at all.
Please stick to the standard pathing, and avoid any bugs or glitches in this map or any map. I'll lift the ban. Happy gaming!
Also note you were not able to help us pinned in the back...
