Google will not ban the account if it follows the Google Adsense policies strictly. You have every right to request and get answer.
it is strange. I know there are tons of online dating sites out there running adsense on their sites just fine. it is recommended to go over the guideline by yourself again before contacting google.
When I checked the URL, there was an Adbrite banner that some might consider borderline "adult". Perhaps Google classified it as such.
Your site will surely be breaking the TOS of Google Adsense, they ban accounts when they find something against there TOS it includes Fraud clicks, content not accepting, etc.
