Chronic Spam Registration through WPForo

Hi there,

We have been using WPForo for a while but have a serious issue with hundreds of thousands of spam user registrations being registered through the forum registration.

The WordPress registration page is completely disabled, so the only place to register is via the forum.

We have the the captcha on the forum registration enabled, but the bots get right through it. We have also since installed CleanTalk to try and stop it, but it has barely slowed the registrations down.

We unfortunately get so many registrations that our hosting service provider has stopped our site from being able to send emails because of all the user registration emails as they assume our website is compromised.

i cant even try Captcha V3 instead because the plugin doesnt allow for use of it.

Please help – is there anything that we can do to stop this? I have applied various suggestions made by WpForo to help with it, but they are not helping.
