Prevent automated spam responses (Bot detection)

We've added Cloudflare Turnstile bot detection as an optional feature for your questionnaires. When enabled, Cloudflare runs invisible JavaScript challenges in respondents' browsers to detect automated submissions — respondents see no captcha or any other visible interaction. 

US Customers 

If you are a US-based customer, you can turn this on yourself by following these steps:

1. Open the menu on the top right.
2. Select Manage teams.
3. Click the team name. 
4. Toggle on "Allow bot checks". 

5. You can then enable it per questionnaire in its Settings...

   

6.  or set it on by default for all new questionnaires (note that it won't be automatically turned on for surveys that were already created, you'll need to follow #5 for them).

   

Customers outside the US 

This feature is available to you at no extra cost. Because enabling it involves transferring respondent data (IP address, TLS fingerprint, and browser User-Agent string) to Cloudflare in the United States, activating it requires a separate contract addendum to cover the data transfer. If you're interested, please contact support@maptionnaire.com. 

How the bot checks show in survey data:

Analysis tool

You will be able to filter out all respondents that have been flagged as probable bots.

You can click on an individual map response and see a symbol of whether it has been flagged as a probably bot entry or not.

In the xslx and geoJSON output

Other ways to limit duplicate or unwanted responses

Bot detection works well together with Allow only one respondent per device+browser, which is on by default and lets each respondent return to their own answers instead of starting a new submission. If people share a device, for example a tablet at an event, use a reset link so each new person starts fresh.

For stricter control over who answers, you can also require respondents to register and log in, or send each respondent or group a unique link.
