Spam bookings can originate from both bots or humans. This article describes both types and explains how OnceHub helps to prevent them.

* **Automated Spam Bookings:** Automated spam bookings are created by bots or automated scripts attempting to submit large volumes of bookings.
* **Manual Spam Bookings:** Manual spam bookings occur when a human intentionally creates fraudulent bookings.
