AntiSpamSFS:
- Can protect any gpEasy form
- Does not add any captcha to your forms
- Can block both robot and human spammers
- Support spammers logging and basic stats (on a per form basis)
- 'Latest Blocked Spammers' gadget (added in v1.2)

With the latest version (v1.3), any gpEasy (core or plugin) form can be protected whether it is reCaptcha-ready or not.

For instance, if you want to prevent emails black-listed on the Stop Forum Spam website to subscribe your newsletter, just add a new form (AntiSpamSFS - Manages forms) with the following parameters:
- Name: Newsletter
- Published: Yes
- Hook: PageRunScript
- Page title: Abonnenten-Liste
- cmd: subscribe
- Use Email: Yes
- Email Alias: nl_email
