Public Survey: Blocking/Filtering Automated Systems

Question

Is there a way to block automated systems (bots) from submitting forms?

The public survey will be on a Government (Drupal) website as a link (opens a new tab/windows), not embedded.

The link is the same URL provide on Survey123 - Submitter Tab - Share this Survey, therefore it is hosted on https://survey123.arcgis.com/share/surveyid browser.

I am not familiar with "challenge-response testing". I am curious to known whether ArcGIS Online provides this capability/configuration on its sites, or is it a third-party app required to be embedded on the  https://survey123.arcgis.com/share/surveyid browser page?

I am having similar issues: Of the 400 survey responses we've gotten so far, we've had about 150 actual humans. The survey is supposed to be confidential, so it will be a hot mess trying to figure out what responses were spam and what were not. For ongoing data collection, I am wondering if requiring a generic verification question to proceed (ie having the user add numbers or something) could help reduce spam?  Has anyone tried that?

Thanks,

Molly

Here's a cross-post  from @ZacharySutherby  outlining the issue and a potential work around, if acceptbale to your IT team.

Wow. We just had about 300 spam responses to a survey.

Any options at all for preventing something like this?
