Use this guide to reduce spammy messages sent through your site's Form Blocks. Although there's no way to block all spam from reaching you, there are a few strategies to decrease the amount.
Why is this happening?
Spambots crawl the web looking for ways to share unsolicited content. They look for email addresses, forums, and contact forms. So, if you have a Form Block on your site, there's a chance you'll receive spam.
Reduce spam using Google reCAPTCHA
The best way to prevent spammy messages through your forms is to add Google reCAPTCHA. Google reCAPTCHA is a tool that distinguishes humans from spambots. It prompts visitors to check a box verifying that they’re not a robot, and sometimes asks visitors to complete another task, like identify a string of letters. Most spambots can’t do this, but your human visitors should have no trouble.
Google reCAPTCHA is available on Form Blocks and Newsletter Blocks. To add Google reCAPTCHA to your forms, visit Adding Google reCAPTCHA.
Reduce spam using double opt-in
Another great way to prevent form spam is to select Squarespace Email Campaigns or Mailchimp as your storage option. Both services use double opt-in, which requires subscribers to confirm their subscription by email.
If you use Email Campaigns, double opt-in is enabled for Cover Page newsletter signup, Newsletter Blocks, and Promotional Pop-Ups. To learn more, visit Building mailing lists.
