Screenshot of New Option:
You have to put a Publisher ID in this option. Usually Ad networks create their own publisher Account and put that Publisher ID in here.
This module is useful to save traffic. Any traffic from the Invalid/Banned/Disabled Affiliate will get redirected to this Affiliate's Account. Make sure this Affiliate Account have all offers pre approved(Use Offer Approval Page to create a rule)
Example 1 : Suppose there was a publisher XYZ in your ad network which was sending Bad Quality/Fraud traffic and you decided to bann that Publisher. But that publisher is still sending traffic to his old Affiliate tracking link. So using this module you can redirect that traffic to your own publisher account . Also you can change the offer using another module (more about this later)
Example 2: Suppose you are somehow getting traffic to affiliate link with as Affiliate ID that do not exisit . i,e. the publisher ID in the tracking link is invalid. in which case the all that trafffic will get redirected to this 'Global Fallback Affiliate ID'
