That sounds like a solid plan! Automating the approval process for new posts using the Dart Nostr library seems like a useful and efficient approach. Using docker-compose to run the service with configurable arguments, such as relays and public keys, is a great way to make it accessible for anyone interested in running the bot.

The idea of marking approved posters to enable auto-approval for future posts is quite clever. It could save time and streamline the process even further. Just be sure to implement appropriate security measures to prevent any unauthorized access or misuse of the bot's functionality.

Overall, it sounds like you're on track with your project! Keep up the good work, and don't hesitate to reach out if you need any more assistance or advice along the way. Happy coding! 🤖💻
