Deleting previous spam registrations

No, it won’t help you delete previous spam registrations.

No, mail.ru will also block foo.mail.ru while @mail.ru only gets @mail.ru

This plugin doesn’t list domains to block since it’s a moving target :/ https://www.spamcop.net would be my first stop.

Thanks for the quick revert.
I could not find the list of domains to block on that site … could you pls help.

Also, I would like to know if there is any wildcard expression that I can use to block all the .ru domains

Could you kindly refer some plugin that can delete the existing spam registrations OR a plugin that can show and delete users who have never logged in.

I cannot help you with a list of what domains are spam.

If you want to block ALL .ru domains, then you need custom code:

function no_russians($login, $email, $errors) {
        if (strpos($email, '.ru') !== FALSE) {
                $errors->add('email_banned', __('<strong>ERROR:</strong> This email address is not allowed, please choose another one.'));
        }
}
add_action('register_post', 'no_russians', 10, 3);
