Thank you for your email. I understand you are concerned that your ad in the OSDC Campaign has been disapproved for hacking as we regard this as Unacceptable Content.
I have looked into this and can confirm that your ad text is in fact in violation of our AdWords policy with the phrase 'start hacking now'. I encourage you to edit this ad text to 'how to prevent hacking' or something of a similar nature that does not appear to be promoting hacking. A change of this type would be in accordance with our guidelines.
