I'm calling rubbish. You griefed on the 11th and 12th of October, you were jailed for these griefs. I do not believe that Migas didn't explain to you why you were jailed, we explain to everyone why they are jailed. Rules are also freely available for everyone to read ingame and on the Forum.
The 12th October grief was to Rescue's house. You though it was okay to damage the house because you though it was a mate of yours. You though it was SnapPvP's house. For the record, this doesn't make it okay.
On the 11th October, your Griefed... SnapPvP's house. He reported it as grief, so clearly you are not a mate of his. What makes you think it would be okay to go attack a house you thought was SnapPvP's, after being punished for it already?
Today you multi-accounted to evade the 4 day ban. A ban that was not permanent. This resulted in your IP ban.
