Public offers are typically available to all affiliates. However, you can restrict access to specific affiliates by using the "Blacklist Affiliates from Offers" feature.
How to Blacklist an Affiliate for an Offer
Navigate to the details page of the offer where you want to apply the blacklist.
Open the Affiliate Tracking tab.
Select the affiliate you wish to blacklist.
Once blacklisted, traffic from the affiliate will no longer be accepted.
A list of blacklisted affiliates is displayed on the same page. You can review or manage this list, including approving previously blacklisted affiliates directly from the list.
