🔍 How it works
When a supporter submits a signup form on Mobilize, a brief automated check runs in the background to confirm the submission is coming from a real person. This happens on every public signup — supporters will always see a short "Verifying…" spinner before their form is submitted.
For the vast majority of users, the spinner completes in a moment and the signup goes through normally. No extra steps required.
In some cases, a supporter may be asked to complete a simple on-screen prompt — a checkbox labeled "I am human" — before their signup is accepted. This prompt appears when the verification step detects something unusual about the request. It is not an error, and it does not mean the supporter has done anything wrong.
📋 Where does verification appear?
Signup verification runs on all public-facing Mobilize signup surfaces, including:
Event signup forms
Group signup forms
One-tap signups from feed cards
Post-signup modals
Event suggestion modals
Signups recruited via Volunteer Schedule
Mobile in-product Attend buttons
Verification does not appear on authenticated organizer or admin surfaces, such as the dashboard or event management tools.
⚙️ How it works for Admins
Signup verification is on by default for all dashboards and requires no setup or configuration from organizers.
🙋 Troubleshoot
A supporter sees the "I am human" checkbox:
This is expected behavior. The supporter should check the box and submit the form.
A supporter says the verification keeps failing:
Ask them refresh their page and try again — most cases clear on a second attempt. If the issue persists, have them reach out to the organization running the event directly.
An organizer is seeing reports of real supporters being blocked:
File a report with Mobilize Support. Please include:
The event URL
The approximate date and time of the issue
A screenshot of the verification prompt, if available
The supporter's general location or device type, if known
❓ FAQ
Will all supporters see the spinner? Yes. Every user sees the brief "Verifying…" spinner when they submit a signup form.
Will most supporters have to click a checkbox? No. Most supporters will pass through automatically without any extra steps.
Is this accessible for supporters with different language settings? Yes. The verification prompt supports localization and displays in the language of the event.
