Finally, my brother had his own theory, "What if google was hacked or modified from an insider or even an outsider?", I gave him a sarcastic look for seconds then thought in myself, "Well, google homepage was hacked not so long ago. Adsense login page went out of service for hours. A few days ago, adwords login page went out of service too. There are no official statements from google or their spokesman GG regarding this web directory filteration issue or any other issues from what I mentioned. Then why do we assume that the google empire is ammune from being intrued?"
Yep, them being hacked is a much more likely scenario than you being penalized for your ODP clone. I would contact them immediately!
