Harry there are a lot of politics involved here. Since your last appeal to get your tags back, the rules have changed so that now votes in favor must be at least eighty percent of the vote. You have many friends in XI that will always be in favor of allowing you back in, but you have to admit, you've had run-ins with people in the past and some of them have a vote regarding your tags. You've never been afraid to voice your opinion on practically any subject, regardless of how some felt about it and that is probably working against you. Needless to say there are some that aren't too anxious to let you back in.
You have left the admin team once and dropped your tags twice, and there are some (even some who really like you) who happen to feel that those who drop their tags shouldn't be able to come back at all, or at least not for a very long time. I'm afraid that dropping your tags was a huge mistake on your part that your detractors will use against you for as long as possible. The debate among the admins to allow you back was very heated at times, and the shake-up in the admin team when you left is still very fresh in many minds.
It's going to take some time my friend, just take advantage of what access you do have and enjoy playing the games.
