Prevent Spam Contacts from Syncing to HubSpot

Spam contacts are created in your store and this article talks about how to prevent them in your store so that Unific doesn't sync them

The most common reason for spam contacts being created in your store is due to spambots. 

Spambots usually target unprotected forms on your website such as newsletter signups, contact forms, and account registration screens.

The easiest and most common way to prevent this is to protect every form on your web site with a CAPTCHA.

If you are using HubSpot forms on your web site, you can configure forms to use CAPTCHA. Here's a HubSpot Knowledge base article on this: https://knowledge.hubspot.com/forms/prevent-spam-form-submissions
