Have you considered just buying a domain to use as a catchall address. That's what I use for the small % of services that refuse my simplelogin emails.
It is a valid approach and good idea. But also ppl who do it should know... it ties all the accounts together through a domain no one else uses. With a privacy mail provider there could be millions of others on the domain. With a prvate domain, not so much. It's one more piece of data that helps identity brokers deduce that account A on site A is the same person as account B on site B.
Some might not care about it. Or, they might. Threat models etc.
A way to create some mitigation of this issue can be done using a service like Njalla or Porkbun where you can make the account annonomously and pay in xmr. Sure, all the bullshit signups are still tied to a single domain but that domain isn't tied to anything.
It's a cat and mouse game, since spammers will leverage this to work around bans or having to subscribe with phone or SMS verification on the major email providers.
These providers often end up on list such as https://github.com/disposable-email-domains/disposable-email-domains
You're trying to bypass an anti spam filter. If there was a consistent way to do that, spammers would exploit it til the vulnerability was mitigated.
I've been using fastmail and it works, but it's on the expensive side, enough to be unattractive to spammers. So that's one approach.
