Spam not being filtered

Why am I getting so much gross spam going through my Contact form? I have reCaptcha set up. They have to check the box that says I’m not a robot. Is there something I need to turn on in order to filter these nasty messages? https://riverviewterrace.com/contact/

Hi @arobix. I think I replied to you on Facebook? Can you let me know if you did not receive that message? Thank you.
