Admittedly the title is pretty sensationalist. The repo activity seems to indicate that the project has some users. It’s impossible to know how many sites or which sites block emails contained in this list and what the impact might be. Even though I think the 7c/fakefilter project is inane, I would hesitate to say there would be no consequences at all.

It’s best to defend legitimate email providers whenever possible. If we don’t, those with an axe to grind get to define the provider’s reputation.

I’d really want to know what’s driving them

likely ego

But did they add addy.io?

Yep.

I’ve already run into a few. I mentally thank them for preventing me from wasting my time and money with them.

And since people won’t use the website, the website won’t use the list. So the list would be useless.
The maintainer seems to have followed the same interpretation, weighing legitimate use against spam use. This is the official response to the issue as of 8h ago:

Dear Contributors,

We value your suggestions for expanding our list of disposable email providers. Your input is crucial in enhancing our tool’s capabilities.

Decision on Gmail and ProtonMail Inclusion

After thorough evaluation, we have resolved not to include Gmail and ProtonMail in our list. Our rationale is based on the following technical and operational considerations:

1. **Reputation and Reliability**
   
   * **Gmail and ProtonMail**: Established, reputable providers with a high trust level for personal and professional communication.
   * **Distinction**: Unlike typical disposable email services, they offer long-term, reliable email solutions.

2. **Active Abuse and Spam Prevention Mechanisms**
   
   * **Effective Systems**: Both providers have robust mechanisms to detect and mitigate abuse and spam.
   * **Proactive Monitoring**: Ensures a secure email environment, reducing the prevalence of malicious activities.

3. **Commercial Intent of Typical Disposable Email Providers**
   
   * **Focus**: Targeting providers driven by ad revenue, facilitating spam/abuse.
   * **Gmail and ProtonMail's Model**: User-centric, not primarily ad-driven.

4. **Domain Limitations**
   
   * **Effectiveness**: Limited domain offerings by Gmail and ProtonMail make them less susceptible to misuse.
   * **Strategy**: Focusing on providers with extensive, rotating domain lists for more impactful filtering.

5. **Individual User Accountability**
   
   * **Accountability Measures**: Both services have mechanisms to penalize users violating terms, decreasing misuse risks.

Summary and Next Steps

Including Gmail and ProtonMail does not align with our criteria for identifying disposable email services. Our aim is to target services significantly contributing to online spam and abuse, without impacting legitimate email services. We have reviewed your list and agree on adding some providers, like internxt.com (Reference). We will also incorporate the obvious choices from the tail of your list. We apologize for the delay in addressing this issue but intend to promptly resolve it by focusing on the most impactful additions.

GitHub blocked me from registering with a Proton domain:

Our abuse detecting systems flagged your account because of the email address you used to register the account. Before we can remove the flag we need you to add and verify a personal, non-disposable, non-aliased email address.

Same. That said, sometimes it’s a config error. I sent a very annoyed email to a website that didn’t work on Firefox, only for them to tell me that it was a bug and that they fixed it.

Simple as, if they don’t even support e-mail it’s surely a rather shite site.

The closed garden corpo-approved electronic message service the github issue is talking about simply won’t do.

Truly a sad day for poppy heads

That comment chain was utterly hilarious. The OP practically wanted to block every email provider in existence.

You know because you can create spam from practically every provider. I guess it’s good that this kind of idiocy is hashed out rather than just being implemented blindly with a pull request.

You cannot even make it past the half-way mark of the OP to realize that the creator has no idea what they are talking about.

Something interesting I learnt about the generated gmail accounts is that they either contain + or an excessive amount of dots, 2 very odd patterns in real, legitimate email accounts. I was able to reliably detect at least 3 or 4 dots in the email itself when it’s using the dotted variation.

Continuing the discussion, the fact that they are so defensive and immediately hide behind moral high ground when someone calls out their mental gymnastics out for the bullshit they are, makes me believe that they are a troll. A child would lose interest after getting so many negative responses.

The behavior you see from the creator is close to a troll tactic called “sealioning”. While refusing to give their own claims any plausible proof (they constantly talk about “tests” they’ve run without any specification thereof), they request elucidation or sources for any contraindicating claims (here in the form of discussions which are held off-platform, e.g. on Discord), but fail to engage with any proof of the contrary (refusing to take protonmail and several other legitimate providers off the list even after talking to the literal CTO) while just reiterating their standpoint over and over again.

All the while, they pretend to discuss sincerely and are always polite and superficially receptive to counterclaims. This is key to their general strategy of eroding a victim’s patience and exhaust their attention. One of two outcomes generally occur:

a) The victim snaps. In this case the troll will claim moral high ground and garner sympathy from 3rd-party observers because of fickle reasons like “there is no reason to insult somebody on the internet”.

b) The victim leaves in order to not appear unreasonable. On a public platform, like a thread, many observers will then grant the “victory” to the troll because their stand point seems strong and counterclaims seem indefensible. This is the ultimate goal of the troll and what makes it dangerous.

Because they want to sell it and spam it.

Looks like someone noticed the PR and panicked. Then people someone crossposted here and people picked up the pitchforks a bit too early.

Yea, I guess it’s impossible to make burner gmail accounts too…

Hmm worrying. I switched to Fastmail too and use a lot of their ‘masked emails’. No problems so far, touch wood

I’m tired of watching bad ideas grow into industry standards.
