Site removed from Google index, few questions

[adrianTNT]

Hello.

One of my sites (technology related articles) was removed from Google index, when I search for "site:mysite" nothing shows up. No traffic from Google eider so I am banned/removed from index.

This happen because I posted some articles from article sites (stupid me) so it must be an orignality problem.

My questions are:
- Is this permanent?
- Does it help if I add more original content or is it a must* to remove all current not-orignal content? Yahoo stil sends some traffic so I would like to keep the current content if possible, and only add more original content.

Thanks.

This in itself is not enough to get your site banned there is a deeper issue.

Possible hack is most likely the issue as Google just doesn't ban sites for copying some content otherwise 90% of the web would be banned.

Look deeper have you been buying links or involved in 3 way linking deals? Ask your host to scan the site for possible redirects and or other forms of a possible hack.

I only had around 2-3 sites linking to this one. This shouldn't be the problem.
Google webmaster tools says "this site is not indexed" or something like that, (all my other sites are indexed ok).
Originality is the only problem I can think of.
DNS and other settings are the same like other sites I have. The other sites are ok.
It had good traffic form Google before it was dropped from index, but now it doesn't show in Google at all, no page, not even a contact page.
