I warned you to stop being a nuisance and pressing buttons after you went into Gavin's house without his permission and griefed his creations under his house. You didn't break rules by griefing but you broke rules by entering without permission.
I am not arguing with you either, I am stating that you broke the rules and finally, I did not jail you 'so [You] spawn up in the air'. As far as I know there aren't incredibly specific options when jailing. Eg. I want to smite this person repeatedly for the duration of their arrest - It doesn't work like that.
