The concept is good, but I'm not sure Slack is the right tool for this. Slack is great for relatively small teams where everyone knows each other in real life and you have relatively tight management control, but it has very limited tools for more "public" membership and appears to not really be designed for that application. For example, you can't restrict people from changing their display name, so it's easy for someone to play the Ender's Game trick of adding a space to their name to appear like someone else. Easy to deal with in a small team, but difficult to manage in a larger semi-anonymous group.
