Blocking disposable email registrations protects WordPress sites from spam comments and malicious users. It also helps keep registration, comment and checkout forms clean and free from fake user accounts.
Block temporary email registrations are email addresses that automatically expire after a specific amount of time and are often used for fraudulent activities like spam, hacking or taking advantage of services with free trials. They can pollute the email database and make it hard for businesses to identify legitimate customers. For that reason, it’s crucial to block such emails in order to maintain a high quality of user base and ensure that businesses are communicating with real people.

The solution for this is simple: there are many tools available that provide a list of known disposable email domains and check them in the pre-user registration action. This allows the system to flag and throttle signups for users registering with these addresses, even if they pass all other technical checks. These tools can be very effective and allow us to strike a balance between ensuring our platforms are safe for users while still giving them the ability to register with their own personal emails.
As a developer, you can use these tools to set up a pre-user registration Action that checks for a list of known disposable email providers and flags users who try to sign up with one of those. This can prevent fake registrations, reduce spam and fraud on your platform and help you to establish a better relationship with your audience.
