FormGlut has several layers of spam protection. Most need no account. You can combine them.

Honeypot (on by default)

A honeypot is a hidden field that people never see but bots fill in. Submissions with the field filled are dropped quietly.

  • Turn it on for all forms in Global Settings › Spam protection › Enable honeypot.
  • Override it per form in Settings › Spam & privacy › Honeypot: Use global setting, On for this form or Off for this form.

Per-form spam checks

In the form’s Settings › Spam & privacy:

SettingWhat it does
Check with AkismetSends the submission to Akismet. Needs the Akismet plugin with an API key. Spam goes to the Spam folder.
Check with Stop Forum SpamChecks the visitor’s email and IP address against stopforumspam.com, a free list of known spammers. Listed submissions go to the Spam folder. Mention this in your privacy policy.
Blocked wordsOne word or phrase per line. Whole words only, not case-sensitive.
When a blocked word is foundReject the submission or Save it as spam.
Max submissions per visitor per hourLimits submissions per IP address. 0 means no limit.
