Obviously your Banned on Google.

I've had four sites banned in the last 4 days from Google so I know all about being banned. It sucks! The Google Webmaster Area takes about 3 days to update so that's no use. Of the four sites I've had banned in the last 4 days only one got a message from Google and that was in the Webmaster Area and was tiny, only showed once and when I went to another page and then back it was gone. It's just a thing saying you can send a reconsideration email etc but of no use.

Not sure exactly what you did wrong but I'm guessing in your case it's quality of content which is very poor.
eg. this is just ripped http://www.ir-scene.com/20169/others...%93-dm999.html

Google is cracking down on this type of stuff. It considers your site of no use.

Basically your fucked. If Google bans your site their's little you can do. If you try and undo everything and even if you write all your own content and make it all unique it still takes weeks to get unbanned and your traffic back.
