FWIW, I wish I had such a thing for the comment above that one :/. One of the only (arguably "the only"!) remaining decentralized platform protocols we have on the Internet is e-mail, and using it for authentication is so much better for everyone than virtually every single alternative (absolutely including even a bespoke username). That tech people, of all people, hate on email so much that they refuse to give it out or use systems built on it--seemingly preferring worlds with walled gardens of centralized moderation and push notifications with permissioned / gated sign-in systems--makes the world universally worse for everyone. Being so uptight about "spam" in general is a big reason why we are falling into the surveillance capitalism dystopia that even end users are finally waking up to hate. (For the record, my email address is saurik@saurik.com.)
Uh no. If you want to test your spam filters go ahead. All they really need is a name and login for me to try their product, if it works well for me I'll be happy to pony up my email and payment information. Otherwise, I'll move along and they won't have an email to bug me with.
