Steps to solve the limit serves issue from Google AdSense

• The account is being evaluated.-When this limit is reached, AdSense is busy evaluating the quality of your traffic. Often, there is no defined amount of time to wait for restrictions to be lifted. As they learn more about your traffic quality, they will automatically review and update the limit.
• Traffic fears that are unfounded-In a circumstance similar to the one described above, your account has been restricted because Google's systems have detected certain erroneous traffic issues. As they learn more about your traffic quality, they will automatically review and update the limit.
