Since 10th December, Substack introduced age verification to login to your account. Unfortunately this breaks the process of deleting an account (which requires you to login).

How can I delete my account without completing the video streamed mug shot age verification process?

support@substack.com autoreply directs you to substack.com/contact -- which also requires you to pass age verification first.

The substack AI chatbot is useless - no hope of reaching a human. The process for cancelling a deceased account doesn't work either as the chatbot can't look up my account using my email address (presumably it is frozen until age verification). Tor and VPNs don't work as my profile includes my location in Australia, and my email address is Australian.

Any ideas? I'm about to cancel my credit card as a last resort.
