This reply by AdSense is the hardest to fix.
If you change theme

If you add more contents

If you wait to get alot of traffic

If you use free images

If you do proper onpage SEO

If you post only human unique contents

If you change AdSense account
Till now, I still don't know how to get a site that Google replied with program policy for approved.
Almost nothing works, if you even ask in the Google AdSense community they don't know why Google reply with this and will only be telling you nonsense.
Anyone has experience
