The Complete Guide to Form Spam Protection

Form spam is a common problem for website owners. Learn how to protect your contact forms from bots and spam submissions with these proven techniques.

Why Form Spam Happens

Bots constantly scan the internet looking for forms to submit spam. Without protection, your inbox can quickly fill up with junk submissions.

1. Rate Limiting

Limit the number of submissions from a single IP address within a time period. FormX automatically implements rate limiting to prevent abuse.

2. Honeypot Fields

Add hidden fields that humans won't see but bots will fill out. If these fields contain data, reject the submission.

<input 
  type="text" 
  name="_gotcha" 
  style="display:none" 
  tabindex="-1" 
  autocomplete="off"
/>

3. CAPTCHA

While effective, CAPTCHAs can hurt user experience. Use them only if other methods aren't sufficient.

4. Email Verification

Require users to verify their email address before processing the submission. This ensures real people are submitting your forms.

5. Content Filtering

Block submissions containing common spam keywords or suspicious patterns. FormX includes intelligent content filtering.
