For past 2 months I've been getting hammered by WPspamAiBot1GPT.  It continues to pollute my mailbox/contact form with realistic sounding leads.  I get over 250 a day.  I tried several captcha as well as turnstile security, it only stopped them for a few days.  Occasionally I get ransom demands, telling me to pay with a gift card if I want the robot to stop the attacks.  Has anyone figured out how to deal with this type of scammers/problem?
