I got this email from them:
Earlier this week our primary upstream provider informed us that your account may be receiving a significant traffic quality deduction for September revenue. In response, we are temporarily holding your September payment while we determine the actual deduction amount.
We had hoped to have these numbers finalized sooner; however we did not receive the necessary data before the end of September's payment cycle.
Once we have confirmed the actual deduction amount we will apply an adjustment to your account and set your account back to PAY status. Your corrected September revenue will be included with your next payment.
Then I responded:
Can you explain to me why my account may be receiving a significant traffic quality deduction?
Three days later they responded:
Our partners are increasingly monitoring traffic on their system, and are
themselves deducting from the payments. These adjustments reflect traffic
from bot spiders and other non-converting traffic that our advertisers
discount to us. Our upstream search providers and our direct advertisers
discount for click bots, PTR clicks, etc.
Then I wrote this today:
Yes, But that is not anything new, that has always been the case. Give me a break Guys...Can you tell me exactly how this affects my account? , Will I get a report of some type?
