If you watch starting at 19:00 you can see me trade Hathaway a bag of black pantherskin gear as well as GEB's and a peacebringer. I petitioned in-game but was told I cannot get them back.... Why not?? It took a long time to get enough money to buy those and I wasn't apart of whatever the reason is that he got banned.... Why do I have to suffer too? All I am asking is for you guys to maybe have a vote to return my hardly earned gear...

Thanks
