CrakRevenue's approach to VPN traffic is more nuanced than a simple block or ban, they have a threshold for acceptable VPN traffic that's around 10-15% of total traffic. Exceeding this threshold can lead to reduced earnings or even account suspension. I've worked with them in the past and found that their support team is willing to work with publishers to identify and filter out VPN traffic, especially if it's coming from legitimate promotional methods. Building on the idea of tolerating certain percent of VPN traffic, it's essential to maintain a clean traffic profile by regularly monitoring and optimizing your promotional channels to minimize VPN traffic. One effective way to do this is by using geo-targeted landing pages that naturally deter VPN users, which has helped me reduce VPN traffic by 25% on my adult site.
