It had to go. When I first set up this contact page, the spam started showing up later the same day. I added a CPATCHA guard and the spam dropped off considerably. I only got SEO promotions once a week or so. It didn't last. The spam went back to daily with all the usual spam subjects coming through. Since no real contact requests showed up, I've disabled the function.
I'm not on Facebook or Instagram anymore. You can contact me via LinkedIn if you are on that platform. I hesitate to say where else you can find me for fear of the spam-bots going after me.
