How to block "images2-focus-opensocial.googleusercontent.com" with CF Firewall?

Hello,
I recently added Hotlink in Firewall Rules. There are no pages that can use my images on their websites.
But one problem is that Proxy from Google is still accessible, so other websites that use Proxy from Google will continue to steal images from my site.

Is there any way to block Proxy from Google?
Please help!

I just tried it and it looks like Google uses a different user-agent:

https://example.com/image.png | Mozilla/5.0 (compatible) Feedfetcher-Google; (+http://www.google.com/feedfetcher.html)

So you could block user agents with Feedfetcher-Google, at risk of (I believe) Google News not showing your images.
