Fake leads

We’ve been getting a ton of submissions through the Contact Us form that say “I saw your ad and am interested. Please get in touch with me soon” or “please send some information to my email.”

 

Those specific words, in that specific order.

 

I have captcha turned on for this form but this is clearly a spam bot.

 

Any insights here on what we can do to prevent this? Huge waste of time dealing with bad leads.
