I just got notice from Google for my city local forum.

************************************************** ******
While reviewing your account, we noticed that you are currently displaying Google ads in a manner that is not compliant with our policies. For instance, we found violations of AdSense policies on pages such as Prijavljivanje. Please note that this URL is an example and that the same violations may exist on other pages of your website.

As stated in our program policies, AdSense publishers are not permitted to place Google ads on sites involved in the distribution of copyrighted materials. This includes hosting copyrighted files on your site, as well as providing links for or driving traffic to sites that contain copyrighted material.

Please make any necessary changes to your webpages in the next 72 hours. We also suggest that you take the time to review our program policies (https://www.google.com/adsense/policies) to ensure that all of your other pages are in compliance.

Once you update your site, we will automatically detect the changes and ad serving will not be affected. If you choose not to make the changes to your account within the next three days, your account will remain active but you will no longer be able to display ads on the site. Please note, however, that we may disable your account if further violations are found in the future.

Thank you for your cooperation.

Sincerely,

The Google AdSense Team

I just removed Ads and then all posible links to warez content (movies, music, games,...)
and instructed my moderators to delete every occurance of suspicious cases.

Would it be smart to reply to Google or they will manage the changes themselfs?
