why did google adsense just diabled my site?

[Kim Yeoh]

here is the email they send to me:
"While going through our records recently, we found that your AdSense
account has posed a significant risk to our AdWords advertisers. Since
keeping your account in our publisher network may financially damage
our advertisers in the future, we've decided to disable your account.
Please understand that we consider this a necessary step to protect the
interests of both our advertisers and our other AdSense publishers. We
realize the inconvenience this may cause you, and we thank you in
advance for your understanding and cooperation.


Sincerely,
The Google AdSense Team"

Do you think it's fair? I never click on my ads, I just tell my classmates and friends and relatives to view my blog, but NEVER did I say to click on the ads? WHAT SHALL I DO THEN
