alt Hacker NewsI configured about a dozen domains to have MX records for the mailinator disposable inbox service for about a decade for free as a gift and the domains were toxic for any other email use case for years afterwards… they were so abused you couldn’t even sign up for most web services with any email associated by the time I stopped renewing them… there are still GitHub lists of disposable email addresses that list to blacklist those domains (and many other), so, I agree. If the big providers don’t offer disposable email addresses there is no good option.

The reason it's toxic is because the Venn diagram between disposable email addresses and email addresses used for CSAM is a circle: If you accept disposable email and allow users to upload anything, you will have CSAM.
Whereas a Fastmail masked email or iCloud relay is still in the backend tied to your real account and identity which means it provides privacy generally for you but is traceable enough that it is unappealing for predators.
Mailinator was an awesome service when it first worked. Thank you!!!
