Stop Signup Spam will prevent user registration of anyone trying to sign up with an the email address or IP address that has been reported to <a href="http://stopforumspam.com/" rel="nofollow ugc">Stop Forum Spam</a>.
Contrary to what the name implies, Stop Forum Spam can be used with any web service, not just forums.
At this time, Stop Signup Spam integrates with:
<ul>
<li>The core WordPress registration form</li>
<li>Restrict Content Pro</li>
<li>MemberPress</li>
<li>Give</li>
</ul>
By installing this plugin, you consent to an API call sent from your WordPress site to Stop Forum Spam after every attempted user registration. The API call includes the user’s email address and IP address.
It is a similar concept to <a href="https://wordpress.org/plugins/akismet/" rel="ugc">Akismet</a>, except instead of checking for blog comment spam, it checks for user signup spam.
Unlike Akismet, no API key is required to query Stop Forum Spam’s database. Partly because of this, I decided not to include a settings page in the Stop Signup Spam plugin. Just activate and you are all set.
The plugin does not log any user registration info. Any data sent to Stop Forum Spam would fall under their <a href="https://www.stopforumspam.com/privacy" rel="nofollow ugc">privacy policy</a>.
Please note that Stop Forum Spam is a third-party service that I have no affiliation with. I just found it, could not find any existing WordPress plugins that worked with it, and built one myself.
It has helped me cut down on signup spam on a free membership site that I run, and I hope it will help you do the same.

The best anti-spam protection to block spam comments and spam in a contact form. The most trusted antispam solution for WordPress and WooCommerce.
Akismet checks your comments and contact form submissions against our global database of spam to prevent your site from publishing malicious content. You can review the comment spam it catches on your blog’s “Comments” admin screen.
Major features in Akismet include:
<ul>
<li>Automatically checks all comments and filters out the ones that look like spam.</li>
<li>Each comment has a status history, so you can easily see which comments were caught or cleared by Akismet and which were spammed or unspammed by a moderator.</li>
<li>URLs are shown in the comment body to reveal hidden or misleading links.</li>
<li>Moderators can see the number of approved comments for each user.</li>
<li>A discard feature that outright blocks the worst spam, saving you disk space and speeding up your site.</li>
</ul>
PS: You’ll be prompted to get an Akismet.com API key to use it, once activated. Keys are free for personal blogs; paid subscriptions are available for businesses and commercial sites.

Nice

Great Plugin

Does the job

It's really good


There are many better ways to handle spam than this garbage. Indeed i with the false positive rate this plugin has it is worse than nothing


Worst antispam plugin


Akismet has been with me since I've been on WordPress and really doesn't miss when compared to other solutions. Keep up the great work!


Doesn't miss a shot


Works very well for basic users so they do not have to buy a paid one just to protect a small site.
