It looks like YPN have started banning some publishers for sending too much international traffic to their advertisers.
Messages like this one have been sent to publishers being banned for this:
‘We have terminated your Yahoo! Publisher Network beta account [ACCOUNT ID] for breach of the Terms and Conditions and/or Program Policies. Your breach includes but may not be limited to sending traffic from users located outside the United States, in violation of Section 11(l) of the Terms and Conditions. In accord with Section 6(a), we will not include such amounts in your payment. We have refunded amounts generated from the non-US users to our advertisers and will pay any remaining amount owed to you in accord with the Terms and Conditions.’
While I knew YPN is in beta and only accepting US publishers I wasn’t aware that their TOS excluded non US traffic. How publishers are supposed to stop this happening without getting into geo targeting ads is a little beyond my grasp.
I wonder if banned publishers will be allowed back into YPN if and when they go international.
Action like this makes me wonder whether YPN might actually be some time away from expanding into an international ad network. Perhaps non US publishers might have a bit longer to wait to be included than they thought.
