How to Stop Spam User Registration in WordPress


WordPress without doubt is the best blogging platform as it has tons of Plugins for your needs and themes as your choice.

But it can also turn into nightmare if you running a multi authored blog, and you set your blog registration to open, there are chances you will be haunted by spammer and BOTS registering on your blog which is very annoying.

I have gone through this headache when I got started with wordpress and by that time I didn’t have this many choice of plugins.

I had to go through the stress of deleting 500+ spam users everyday.

And it was not that easy as marking all and deleting them, as I have a multi author blog where other authors guest post.

So if you’re experiencing similar situation then below are the Best WordPress plugins to help stop spam registration.

1. Wanguard

This plugin is very good at stopping spam registration and making your database clean. I’ve used this plugin for a very long time and many of my niche sites are still using this plugin.


As this plugin is free and does it work very effectively.

How it Works?

When an user try to register on your site, WangGuard will check in its database if the user is a Splogger or spam-user.

If WangGuard determines that the user is a Splogger, WangGuard won’t allow the user to register on your site.

The best thing about it is you dont need to put any kind of filter in the user registration page (eg captcha). Which I hate.
