This is very unfortunate that your adsense account has been disabled by Google. Generally this happens when you violate the terms and conditions of Google. The reason in most of the cases is invalid clicks or self clicks. Google keeps an eye on your clicks and if it finds any suspecious activity and is sure that the clicks are invalid then it disables the adsense account.
You also need to keep an eye on your account and if at any point of time you find that there is sudden increase in the clicks in your account you need to report it to google to avoid such type of inconvenience.
You can also post your query in the adsense forum for more details. HSR has no role in approving or disapproving any adsense account.
