I tend to think that complaining that way; even if you are successful and reinstated, you will probably be placed on page 500. So in the end, it would still be equivalent to a ban. What I wish; is for there to be some way for someone at google to personally tell you what you did wrong if you were manually banned. I've mentioned this before, but it feels like I've been convicted of a terrible crime and I have no idea what I did. It's one thing to lose ranking but to be completely banned is another thing.
