Spam protection overview

Most form spam comes from boring bots, not motivated humans. That means a stack of cheap filters catches almost everything, and the remaining signal you can train against per-form. Formspring runs every submission through six layers:

1. Honeypot - hidden field bots fill but humans never see. On by default. Field name configurable.
2. Rate limit - per IP, per form. Hard cap on burst rates.
3. Captcha - optional hCaptcha or reCAPTCHA. Toggle per form.
4. Custom rules - regex, keywords, blocked emails. You maintain the lists.
5. Akismet - Wordpress's veteran spam classifier. Bring your own key (Pro and above).
6. AI moderation - Pro plans and above get a model-based moderation score on every submission.

Each layer can flag a submission. Flagged submissions go to the spam folder. Nothing is dropped silently - everything is visible and recoverable.

Tuning per form

Settings live on the form's edit page:

• Honeypot field name
• hCaptcha enabled + site key + secret
• reCAPTCHA enabled + site key + secret
• Akismet enabled + key
• Custom rules: regex array, keywords array, blocked-email array

The dashboard also surfaces the most-common spam reasons over the last 30 days so you can spot patterns in your inbox.
