Show HN: List of disposable email domains to prevent fake registrations

Sorry, but if an unknown and untrusted site demands my "real" e-mail address, I just won't register. If they don't accept a disposable e-mail address, what that says to me is that they want to make it harder for me to unsubscribe from any spam they might send me. Or maybe they want to track me across multiple sites, which I don't want either.

The one I use isn&#x27;t on it, and thank goodness.<p>I use an email proxy exactly because I&#x27;m trying to protect my privacy and to cut down on spam email, as it helps me determine its origin without exposing my real email and let my blacklist or discard that proxy email address.

There are some very odd inclusions in this list (which i think, like most of HN people should not use).<p>&gt; kemptvillebaseball.com<p>&gt; isukrainestillacountry.com<p>These seem like people&#x27;s project domains or team domains, and got swept up in some sort of strange authenticity list. Unless the domains were hijacked for spam, it doesn&#x27;t seem like a player on that baseball team is fake.<p>Relatedly, does anyone know what happened to Mailhero? I used to use them, and it kinda became a problem when my emails stopped arriving, and i miss the service.

linus-torvalds-fuck-you.jpg to everybody requiring email except those who accept any string which validates as email.<p>I have seen many cases where you had to enter your email to just download something or sign-up to just take a look at a web app you probably aren&#x27;t going to use. Obviously I always enter a disposable (or completely random) email and random Dohn Joe personal details in such cases. I am only willing to give my real email to the services I am surely going to use actively. If you force me I just go away.<p>And my actual emails (personal and work) in fact are on Tutanota and on a company domain. Whoever offers a paid product and requires GMail can double fuck off.

Seems like you’d be unable to block iCloud’s relay emails, they use the icloud.com domain. Fastmail’s masked email addresses use fastmail.com.

One of my domains is on here and it doesn&#x27;t offer public disposable email. I wonder if there&#x27;s a libel case to be made here...

Disposable email is the only reason you can sign up to a lot of things online, the amount of spam that comes from these hundreds of mildly interesting sites is abysmal. And as a result your mail could end up in multiple datadumps yearly. No thanks.

That&#x27;s funny, but it still doesn&#x27;t stop me from feeding you a fake redirection to a legitimate email, which is what you should <i>actually</i> worry about. If you want to enforce a dystopian level of authenticity on your users, you should make a whitelist, not a blacklist. Coincidentally, you&#x27;d also be losing my patronage, but I suppose that&#x27;s the cost of &quot;progress&quot; in web development.

Why prevent registrations from disposable emails?<p>The reason people do it is because they got burned in the past with websites that started spamming them&#x2F;were not as advertised.<p>Rate-Limit accounts from disposable emails if you must, but if you see activity past the duration of the disposable email, offer these accounts a way to transfer over to a permanent email.

This is a cat and mouse game. And the list seems very small. Like a fraction of a fraction.

Note: If you want to report a wrong email domain, please hit the &quot;Ctrl+F&quot; in your browser and search in the list if the domain you want to &quot;report as wrong&quot; is in the list first. Thanks :)

If you own a domain you have as many as you want. But GitHub did some sort of check which caught me out. Not sure what that involves?

Quick, someone add your most hated mail provider to the list.<p>Hope it gets vetted … SOMEHOW!
