The plugin is built to keep stuff simple. If you need a complex web form or if you need a form builder, please use one of the form plugins you can find in the WordPress repository. To use the “Block countries” feature we use the IP to Country API from Country.is. They offer a free service and you don’t need an API key.

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.
