I am deactivating the plugin until I get a response as it is a problem for my client.

Hello @cdgweb.

I have changed the filtering rules in our cloud for your site. Legitimate requests will no longer be blocked. You can enable the plugin.

The reason of incorrect filtering is the cache. Please let us know which caching solutions you use.

I use Swift Performance Pro

We will test the collaboration of plugins in our environment and contact you within 3 business days.

Hello and thank you for waiting.

We have fixed the issue. Please, re-install the CleanTalk Anti-Spam from this archive:
https://github.com/CleanTalk/wordpress-antispam/releases/download/fix-version/cleantalk-spam-protect.zip

The update guide is here:
https://cleantalk.org/help/update-wordpress

Don’t forget to refresh your website cache if you use any.
