I typically use throw away email addresses instead since they're free. If I actually want to use the service/account some day I'll sign up properly.

I expect someday the primary email providers will generate aliases on demand.

It's not a literal alias, but it works out fine.

One of these days I'm going to propose the Thunderbird + K-9 mail addons that say 'set the sent from email address to be equal to the sent to email address', that way if [email protected] is the recipient, it will be the sender to any replies, rather than the MUA default replying with [email protected] (but that's a separate discussion)

The example above is about giving a direct line to be contacted through email on a personal site or blog, heck even a professional one.

I know at least ProtonMail does it. But also theres the email#[email protected] trick that works nicely enough.

I guess its because they do want legitimate people to reach them easily (students, collaborators etc) and if spams do go through — well they'd probably ignore it, just like they ignore other emails.

I use anti spam addresses to register to new services.
