You were building some unfeasible skybase out of metal props on top of a huge tree, you'd previously placed a load of huge props all around Little Israel, and then blocked the entrance to ghetto with a floating base which you left there. Your ghetto base inhibited RP and prevented cops from entering the ghetto during active RP.
Then you were next at harbor, again in a floating base made out of random materials and metal and just placed on top of a tree.
This is your 5th PET abuse incident, so I would argue a blacklist was justified. Good luck on the appeal regardless!
(I comped you, by the way)
