I was the staff that took your flags, you had them removed for the reason you admitted to on the appeal. You had a previous warning for PET abuse recently and you very clearly didn't understand the PET flag rules so you don't deserve to use them, in my opinion you should have 2 options, wait a month or 2 before appealing again OR pay for your flags back.
