I am sorry you got banned. I did see your profile and I thought about saying something to you but it seemed in the grey area so I left it alone, I wish I had said something. I think since bra shops have become banable they have started getting stricter on other images as well.
As for how long your ticket will take they say fourteen days it could take longer or less. The last ticket I filed took a month and a half the one before that two days. It depends on how many people are in front of you. Do not send more then one in or it will clog the system and make them go slower, after two weeks you can PM a Mod and ask them to check on your case. Keep your reference number for that.
Moderates do try to be fair but they are only human and someone might see something different from someone else. I know I have reported signatures I consider breaking the TOS only to have one Mod tell me no it is fine and another say it is breaking the rules. From what I have read over the years usually one Mod does not make the decision to permanently ban someone, it is usually several who decide that.
If a Mod is treating you unprofessionally you can report them to Gaia administrators though an email. I don't recall it off the top of my head but I am sure I could find it for you easy enough.
