I'm pretty sure the logs RedPowder posted are from just before you were banned and during the lag. You had no reason to be spawning that many chairs and it is pretty obvious that you doing so would cause issues for the server. Looking at the logs you were spawning chair after chair after chair without stopping. It even looks as if you continued trying after the stacker restrictions went off.
