I´m currently using on my wordpress website Contact Form 7 and Google Captcha, but lately I get lots of spam to the point where I have to turn of the plugin. For example, 2 days ago I received over 200 emails with a V3 captcha from Google. It looks like an attack as I get 3 or more e-mails per minute until I have to turn off the form.
Do you know what else I can do? I had to disable the forms.
