From what I understand, PageFair is also running an advertising network to cover their costs and that&#x27;s why they need to be whitelisted. Our solution doesn&#x27;t display any ads or messages to the visitors of websites which use our service. I&#x27;ve heard their reporting is very basic compared to ours, but would love for someone to do a thorough review. We also offer an API.<p>The PageFair hack was very scary and a good reminder to all companies that require the use of external JavaScript by their users. We currently don&#x27;t support subresource integrity, but it&#x27;s now at the top of our to-do list. Thanks for the great feedback!
