Yes. I read these guidelines. As per this "The following markets support the Adult Advertising Program: Canada, France, Germany, Republic of Ireland, United Kingdom, and United States."
I have advertised for United States only. Again they put forth the following:
"Advertisers must apply to participate in the Adult Advertising Program, and agree to the Terms & Conditions as well as the Adult Agreement. Additional content restrictions may apply. Adult ads may not be distributed through all of the advertising distribution options and may appear only in text search ads. If you would like to apply, please contact Customer Support. Your application may be considered separately for each country that you want to display ads in."
May be I need to contact the customer support. I am little confused.
