This plugin protects your blog from spam and is only needed if you have comments enabled or if your form plugin integrates with it (e.g. Gravity Forms). It does require a paid subscription, but it’s one of the best anti-spam plugins out there. You can also opt for it in a Jetpack bundle.

If you want a free anti-spam plugin, look into Antispam Bee: https://wordpress.org/plugins/antispam-bee/
