It's not a necessity. I just refuse to unban an account I cannot properly validate or check on. There are still some aspects of your profile that are locked down so I still cannot fully validate your account from the original banned user you shared an Ip with.
For the safety of Skial, I am going to keep the ban in place. You MAY appeal again in future, this doesn't mean future ones won't be reviewed. Each admin checks bans differently, some are more critical than others. I am very critical with protecting our community.
