reCAPTCHA v3 leading to more spam

We had to upgrade to reCAPTCHA v3 from v2.  I am seeing a lot more spam coming through the sites... wondering if anyone knows how I can adjust settings or something to help.

thanks

It seems to happen to the use of Wordpress too, and for a quick fix...
The only way to get around this at the moment is to revert back to the previous version 7.5.05 and use captcha v2
and a workaround was suggested - The change suggested is a temporary hack, not a fix.  
It looks like there is a logic issue where failing to provide the g-recaptcha-response allows the submission through.

This is a _very_ unofficial change on my part, but it seems to work for me.

Edit line 114 of modules/recaptcha.php (version 5.1)

It reads:

return $spam;

Change it to:

return true;


This will change it so that any submission that does not attempt the Recaptcha V3 validation will be rejected.

thanks, so this is something that they are trying to fix... it is a known problem?  Do you think they will be able to fix it? - thanks.

Not necessary so better to post to the forum as it may be a known issue on reCAPTCHA or the website plugin.  Earlier post suggest plugin issue.
