Well today Google disabled my account because of invalid clicks. I think that I was clickfrauded or something like that. Any ideas?

Can I see a screenshot of the invalid clicks screen? You might want to contact Google Adsense support and work it out with them, they are usually pretty cooperative--unless you got someone to click on your ads for you or if you clicked them yourself But yeah, clickfraud does happen and I know there are some special AdSense plugins for WordPress and other CMS systems like Joomla that have clickfraud protection built into them.
