Descripziun
We’ve all had this problem. A group of spammers from mail.ru are registering to your blog, but you want to keep registration open. How do you kill the spammers without bothering your clientele? While you could edit your functions.php and block the domain, once you get past a few bad eggs, you have to escalate.
Ban Hammer does that for you by preventing unwanted users from registering.
On a single install of WP, instead of using its own database table, Ban Hammer pulls from your list of blacklisted emails from the Comment Blacklist feature, native to WordPress. Since emails never equal IP addresses, it simply skips over and ignores them. On a network instance, there’s a network wide setting for banned emails and domains. This means you only have one place to update and maintain your blacklist. When a blacklisted user attempts to register, they get a customizable message that they cannot register.
For advanced documentation, including how to use on WooCommerce, please visit the Ban Hammer Wiki.
Credits
Ban Hammer is a very weird fork of Philippe Paquet’s No Disposable Email plugin. The original plugin was a straight forward .dat file that listed all the bad emails (generally ones like mailinator that are disposable) and while Ban Hammer doesn’t do that, this would not have been possible without that which was done before.
Many thanks are due to WP-Deadbolt, for making me think about SQL and TTC for StopForumSpam integration. MASSIVE credit to Travis Hamera for the StopForumSpam/cURL fix! And then props to Helen Hou-Sandí for not using curl at all. Protip? Use WP_http instead!

Installaziun
Single Install
After installation, go to Tools > Ban Hammer to customize the error message (and banned emails, but it’s the same list from your comment moderation so…).
Multisite
After installation, go to Network Admin > Settings > Ban Hammer to customize the error message and banned email list. This will ban users network wide.
FAQ
- If I change the blacklist via Ban Hammer, will it change the Comment Blacklist?
-
On single site installs, yes. They are the exact same list, they use the same fields and they update the same data. The only reason I put it there was I felt having an all-in-one place to get the data would be better.
- Does this list the rejected registers?
-
No. Since WordPress doesn’t list rejected comments (your blacklist goes to a blackhole), the rejected users are similarly lost forever.
- Where did Stop Forum Spam go?
-
This plugin no longer uses Stop Forum Spam. If you need that feature, please use Stop Spammer Registrations instead. They did it way better.
- Does this work on MultiSite?
-
Yes it does, but a little differently If you’re using multisite, instead of pulling from the comment blacklist (which is per site), you have a separate list off Network Admin -> Settings. This is because you only want to have the network admins determining who can register on the network.
- Does this work on BuddyPress?
-
Currently yes.
- Does this work on WooCommerce?
-
Yes but… You have to make your own hook because WooCommerce doesn’t use the normal registration functions. Don’t panic. I have directions here.
- Can I block partials?
-
Yes but not wildcards. If you put in
viagrafor example, you will block[email protected]and[email protected]so please use this carefully. If you put incookiethen you’ll block[email protected]and everyone would be sad.If you want to block everyone from all subdomains (like
[email protected]) then you can block.example.comand that will block all the subdomains. - Why doesn’t this work AT ALL on my site!?
-
I’m not sure. I’ve gotten a handful of reports from people where it’s not working, and for the life of me, I’m stumped. So far, it looks like Zend and/or eAccelerator aren’t agreeing with this. If it’s failing, please post on the wp.org forums with your server specs (PHP info, server type, etc) and any plugins you’re running.
Reviews
Seems to work
Sems to do what it says on the tin. Would be good to be able to automatically pull in a spam domain list such as https://github.com/wesbos/burner-email-providers
Great work, easy setup works as promised
Super Thank you
Good!
A question:
It works only with the @ symbol (i.e. @ domain.com) or I can also enter just „domain.com“?
EDIT:
Users can find a long domanis blacklist here:

Thank You
Thank you for this well needed plugin
As an idea, how about adding a link url for admin to create page which redirects the user to a page.
Thanks again
Works 100%
Isn’t it great when a plugin just works 100% with no ifs or buts…
Thank you.
Please keep this updated!
Brilliant!
This plugin has saved me so many sleepless nights, being hounded by a troll is not a nice thing at all. This plugin has at least given me a fighting chance to make it slightly more difficult for the person because now a new email address will be needed to be created next time he registers.
Thanks Ban Hammer BIG thumbs up from me! 😀
