Antispam for Elementor Forms adds two methods of preventing spam submissions to Elementor Pro forms – checking the form contents against the WordPress comment blocklist, which is automatically synced daily, and a JavaScript-based honeypot field, with an optional minimum time to fill out the form.
Privacy disclaimer
This plugin uses the WordPress comment blocklist from GitHub (https://github.com/splorp/wordpress-comment-blacklist, via the raw.githubusercontent.com domain). It is synced daily. Your server’s IP address will be shared with GitHub when this happens. Their terms of use can be found here: https://docs.github.com/en/site-policy/github-terms/github-terms-of-service and their privacy statement can be found here: https://docs.github.com/en/site-policy/privacy-policies/github-general-privacy-statement No data about your users is shared.

AP HoneyPot WordPress Plugin, based on Jan Stępień’s http:BL, allows you 
to verify IP addresses of clients connecting to your blog against the Project 
Honey Pot database. Thanks to http:BL API you can quickly check whether your

creature. Communication with verification server is done via DNS request 
mechanism, which makes the query and response even quicker. Now, thanks 
to AP HoneyPot WordPress Plugin any potentially harmful clients are denied 
from accessing your blog and therefore abusing it.

Hard to believe I've been using this fro over 3 years, and the previous one before for even longer. No I wonder this is still being maintained, but still using in the meantime. 

Updated 3 years ago and still works great
