There is one thing I need to ask before I can ultimately make a decision-- will I be able to trust you on this account?
I ask this because you have been banned 3 other times for different reasons-- your first ban was for griefing Radlam; your second was for being disrespectful after being warned several times; your third was using a 'hacked' client to go into "Derp Mode."
Now this is your fourth ban. This is a sincere apology, but most people that have been banned more than 3 or more times often do not come back on the server because of their dangerous actions that recur at some point again.
I want to absolutely be sure that you won't repeat any past mistakes again. You already have quite a few offenses recorded on your account history here, and I'm afraid to say that if I do let you back on and you get banned once more, you may not have another opportunity to appeal after that.
