Well as far as being stuck in a rock 3 options, have an admin teleport you out, starve to death or suicide. Yes hacking WILL get you banned from the game. When you start the game VAC scans your game files. If it finds something you are flagged and get banned during the next ban wave. There is no way around this and only 1 case was ever recorded of an accidental VAC ban during MW2. Unless you are a genius coder who writes a way to convince VAC that all the files are in order when they are not and never share your code with anyone you will get banned.
I get how it works now. Hindsight, I should've realized being banned from a game just to get unstuck in one unimportant server was a dumb consideration. I don't even play on that server anymore since a small hostile clan moved in, so I found another low player one.
I should've researched a little more and I would've eventually found the F1 function. I'm good now and definitely NOT wanting to cheat, although I am on the fence of getting my own server and going nuts with admin tools.
