Checks field content and block submitting base on your keywords. Blocking IP, Country is only supported in the Pro version.
Security History
What It Does
BSK Forms Blacklist scans form submissions in Gravity Forms and Formidable Forms against a list of keywords you define, blocking entries that contain matching content. The free version handles keyword filtering, while IP and country blocking are locked behind a paid upgrade. It is a lightweight rule-based filter rather than a full anti-spam suite.
Who It's For
This plugin fits small-to-mid-sized sites running Gravity Forms or Formidable Forms that need a simple way to reject submissions containing specific words, phrases, or invite codes. It is particularly useful for event registrations, gated membership signups, and job application flows where a curated keyword or invite-code list is the primary gatekeeper.
Who Should Skip It
If you need IP-based blocking, country filtering, reCAPTCHA integration, or behavioural spam detection, this plugin's free tier will frustrate you since those features require the Pro upgrade. Sites with high submission volume or those needing hands-off spam AI are better served by a dedicated solution like Maspik.
The Bottom Line
BSK Forms Blacklist is a focused keyword and invite-code gate for Gravity Forms and Formidable Forms, scoring 63.87 out of 100 with strong ratings but limited reach. Its biggest drawback is that IP and country blocking are paywalled, so users who need those features must compare the Pro price against fuller alternatives like Maspik. Reasonable choice for small sites with simple word-list needs, but most spam-heavy deployments will outgrow it quickly.
