I banned you for griefing 200+ blocks in someones house. I'm sorry to hear about that but it doesn't give you the right to destroy other peoples things, which in turn makes them feel bad. Your friends were wrong, the rules are clear and them breaking more rules, namely the spamming one isn't helping. I will lessen the ban but not remove it. It is no at 5 days, because you were apologetic.
Also moved to SMP appeals section.
