Thank you for taking the time to plea.
Here at Famcraft, we do believe in 2nd chances. Unfortunately, you've already had a 2nd chance, and proven that things are not going to work out for you here.
After you returned from your first ban for griefing, you were asked to read the rules. You chose not to, and did as you pleased instead, with no regard for our rules.
Then, when you were caught and banned, you chose to come to our irc chat, and swear on our family friendly server. I am sorry, but we simply will not tolerate this type of behavior here, ever.
I do hope you will find another server you enjoy, that has rules that better fit your needs as a player.
