Hello, @indyparker
Do you get the Anti-Crawler blocking screen only in incognito mode? Are you redirected on your website after 3 seconds?
Make note, it’s normal to see the Anti-Crawler blocking screen in incognito mode. The feature reads the cookie, if there is no cookie set – you get the block. Incognito mode has no cookies set.
If you don’t want your visitors to see the Anti-Crawler screen in incognito mode, disable the Anti-Crawler option:

It is even whitelisted in SpamTalk and it is still happening.
It takes some time to update the personal lists. Please, press the button “Synchronize with cloud” in plugin settings to update your personal lists immediately.

Also, I need to check if Anti Spam affects my CDN?
The Anti-Spam plugin is fully compatible with CDN and we haven’t received reports yet about such problems. I can only recommend you to disable the plugin and check if the issue still persists.
Thank you.
