What’s Fixed
Some real visitors — especially people using browser autofill on mobile or
submitting from in-app browsers like Facebook’s — were seeing “Submission
blocked for security reasons” on hosted and embedded forms, and their
submissions were lost.
Improvements
- Suspicious submissions are no longer rejected outright. The visitor’s browser
completes an invisible verification check (powered by the open-source ALTCHA
proof-of-work challenge) and the form submits itself — no question to answer,
so genuine leads aren’t lost to false positives. - Fast submissions are no longer penalized: people who autofill a form can
submit after 1 second instead of 3. - Visitors who open a form, get distracted, and come back later can now submit
for up to 24 hours (previously 1 hour). - Submissions that pass the invisible verification are flagged in the
submission details so you can review them if needed.
Bug Fixes
- Fixed browser autofill triggering the hidden anti-bot field and blocking
legitimate visitors from submitting.
