You would be best speaking to one of the team mate.
However, I would guess that as you have been a member of the forum for 9 years and only had a few posts up to recently and when you discovered that you require 100 posts to enable you to advertise your car, you quite blatantly started posting heavily to get your count up to 100 so that you could sell your car.
Now correct me if I am wrong, but would you continue to have the same posting activity once you get your advert approved?
As I have said best to speak to a team member for clarity.
