1. You’re right, it was still active. I’ve disabled it.
2. Adding .*params+ to the Exclusion Signs does exclude this ajax call from cleantalk checking (I’ve test that with s@cleantalk.org)
3. You mentioned:
   > I’ve analyzed your site’s requests and noticed that some important parameters are not intercepted correctly by the plugin. This might cause the issue. Please do the following:
   > 1. Update the Anti-Spam plugin by following this guide: https://cleantalk.org/help/update-wordpress
   > 2. Set the cache update time on the site to no more than 24 hours (it’s important).
   > 3. WordPress Admin Page → Settings → Security by CleanTalk → General settings → set the “Set cookies” option to “Alternative mechanism” → Save Changes.
   > 4. Clear the cache.
   
   Can you tell me what problem you observed which those steps would solve?

Thank you!

Update: It appears that the latest version of the WP plugin (6.61) solved this problem (or else something else changed during the same period). Thanks for your help!
