Abuse of staff powers should result in at least a demote. Charging back always results in a perma, but people have been forgiven in the past, and I don't think you have done anything that should make you exempt. Alting has also been forgiven, but is in my opinion the greatest argument for keeping you permad. You have done a lot wrong, but none of it indicates that you will be a hinderance on the community if you return. I know that you have the ability to contribute to the community if you return, so I am going to be +1, although I can see many reasonable explainations for other staff being -1. It might be recommended that you are banned from returning to staff, and potentially banned from purchasing custom content if unbanned, but that does not affect my overall vote of +1 for unban.
