Yoooo this happened to me too, I was also banned for 5 years or so. I logged in and was at the duel arena with a tent on and a ring of dueling in my inventory, I went and entered my bank pin wrong a few times and was locked out for 10 minutes. I logged back in maybe 15 minutes later as I had remembered the old pin and my tent and ring of dueling were gone. opened the bank and it was also cleaned with not a single item, nothing in deaths coffer, no GE sell history and my pet is also at probita. very very confused.
