Google's ReCaptcha v2 seems pretty ineffective nowadays, it would be great if Webflow added some functionality to allow Honeypot fields which filter out automated spam that has made it past ReCaptcha.
I use the Basin (usebasin.com) services for many of my clients sites, but it seems a waste not to use Webflow forms, especially as the client can then access everything in one place.
The Basin team has a simple implementation for Honeypots on their service which keeps out all automated spam (placing it in a spam folder): https://usebasin.com/docs/features/spam-filtering
Would adding this html to the Webflow form work?
<input type="hidden" name="_gotcha"></input>
