Tell HN: Vercel flags accounts using protonmailI attempted to sign up for Vercel today using my protonmail account, and was flagged on the sign up page with a message that I would need to email [email protected] to proceed. I emailed them asking to register, and they responded a day later saying I'd need to sign up with a different email provider. I'm not sure why they would go out of their way to flag proton? 10 comments
