How to stop spam user registrations on your WordPress
Cerber Security has several anti-spam and anti-bot features which can be enabled simultaneously to stop registration spam nightmare.
Enable an antispam engine for the registration form
The fastest way to stop spammers is to enable the antispam engine for the WordPress registration form. To enable protection:
- Go to the Antispam plugin admin page
- Enable Protect registration form with bot detection engine in the Cerber antispam engine section
- If you have a separate, non-standard registration form or a membership plugin, enable Protect all forms on the website with bot detection engine
- Click the Save Changes button
Change the default registration and login URL
The next thing you need to do is to change the default WordPress registration URL to a custom one. That allows you to block automated spam attacks. Follow this guide: Custom login and registration URL for WordPress.
Set the limit on user registrations from one IP address
The third step is to set the limit to the number of user registrations from one IP address. By default, three user accounts are allowed to be registered from one IP address within one hour. This feature is available in Cerber Security Pro.
- Go to the plugin admin Dashboard
- Click on the Users tab
- Enter appropriate values in the Registration limit fields
Block new user registrations from specific countries with GEO rules
The country-based GEO rules enable you to set a list of countries from which users are permitted to register on your WordPress. If you want to get new users from your country only, this is the right way. GEO rules are available in Cerber Security Pro. To create the list of the countries:

Otherwise, if you want to block registrations, click the second option Selected countries are not permitted to Register on the website, other countries are permitted to.
- Click the Save all rules button.
