This plugin works as expected; killed all spammers and false/disposable email addresses which is what I needed for years! No more spammers – wonderful!. |
- Works well
Started getting bot registrations so installed to block signups from a specific domain. It works and the list of already blocked domains is very big, all temps emails or spam emails.

@rik0399 - Perfect and easy
Thanks!
@andrzejc - My site is much safer!
The preemptive domain check is a must for any serious registration system. This was the best solution I could find and it works really well
Paul H - Perfect plugin to block disposable (but not only) email
I sent an email asking to modify the plugin to be compatible with my registration form and the team, really very responsive, did it in a few days.
Then I uploaded a file with more than 22000 disposable email domains to block them in my users registration page. The plugins works perfectly without slowing down the registration process
