As an authority on ignoring mods and getting banned, I think I can safely say that the mods are just people like you and me. You got caught up in what you were doing, and they got caught up in telling you not to and then banning you for it. Only when they get caught up, they have more power.
I say, lick your wounds and move on. If this is the first time you've gotten banned for something you didn't think you deserved to be banned for, you have been playing it too safe. As the guy who first took me mountain biking said on our first ride, right before going a$$ up and landed on his head, "If you ain't crashin', you ain't ridin' hard enough."
EDIT: In most instances, I deserved to be banned for what I was banned for...and if I'm being honest, I have many times posted things I knew I would be banned for, and did it anyway. It's kinda' my thing.
