Ask HN: Is a Geo-Based Audio Chat App Viable? (For the Blind Community)

Hi hackers, I'm a blind programmer who loves chatting. Text chats with screen readers aren't ideal, so I'm building a location-based audio chat app for easy neighborhood connections. Think of it as an audio-based YikYak for your area.

The technical side is manageable, but I need help with the human aspect:

1. Spam Control: How can we prevent misuse? 2. Monetization: How can we discourage self-promotion? 3. Safety: Would age restrictions help combat bullying?

Looking for insights from product managers on tackling these non-technical challenges. Thanks!
