How to block a spammer who keeps completing the contact form

Hi
Does anyone know how to block a very annoying spammer who keeps completing various infusionsoft lead capture forms we have on our website. He’s doing it to promote his dodgy product. We delete him every 1 or 2 weeks and he keeps returning and filling another form. He’s also doing it on another infusionsoft account we manage for a client.

thanks
A

You can’t block that person specifically, but if you use a third-party like Zapier or Integromat you could have all of your lead forms trigger through that third-party and filter. If the email matches the spammer, it can automatically trigger that person for deletion
