I've been in a couple channels with several hundred people. The admins handled it by shouting until everyone was quiet, enforcing one person speaking at a time, and swiftly muting, moving, or banning anyone who disobeyed. I'm not sure if Discord's API is flexible enough for a bot like that.

The API is flexible enough for a bot like this, I'm contemplating opensourcing mine at some point! :)

Please do, it would be an actual act of charity! I've left a lot of interest i 8 servers due to the voice chat being clogged.
