Disposable Registrations Killer est un plugin WordPress qui empêche vos visiteurs de s’enregistrer avec une adresse email jetable. Au moment de l’inscription, le domaine de l’email est vérifié contre une liste. Si l’email est considérée comme jetable, l’utilisateur doit entrer une adresse permanente. Le but est de réduire les inscriptions “fantômes”.

Disposable Registrations Killer is a WordPress plugin that prevents people from registering on your blog with a disposable email address. During registration, the email domain is checked against a list of disposable services. If it’s deemed disposable, the wannabee member is asked to put it another address. The goal is to cut on “ghost” registrations.

    as undisposable.* seems to be offline for a long time I started my own service which is free for everyone who needs it. You can check online if a domain belongs to a provider for disposable emails or if it is a real address.

    Have a look at http://www.block-disposable-email.com/cms/

    Would be great if you integrate it to your plugin.

    Release of Disposable Registrations Killer v1.2

    A POT file has been added so that you can localize the plugin in your language.
    English and French are covered by default but feel free to send in your translations : they will be added to the future releases.

    Disposable Registrations Killer v1.1 is out.

    The plugin is now fixed and operational, correcting the bug in v1.0 which considered all email addresses as disposable. The code is leaner and I’ve added language strings, localised in English and French at the moment.
