Visitors dropped after last week of September 2014

[capulkit]

Hi,
I run a website which has classifieds, forum and article section in it. Site used to receive 800 visitors on an average daily from google.
But suddenly from last week of september google visitors are reduced to only 300. Mainly forum lost the visitors.
Are all forums affected by google update or its just our. We dont have any copied content on our site.
Its highly moderated.
Google wants us to advertise on their adwords?

Is this the site that you asked about in the AdSense forum here?...

Google Adsense not approving second stage-Have lot of unique content

Adsense feels site have law content.

If your content was that marginal, that might still be the problem.
