I think the average server size here is in the ballpark of 1200 people.

These are servers that asked to be advertised by Discord ("Discovery"). These are unlikely to be any kind of servers used for private or even semi-private discussions. You likely don't know most of the people on the server.

Most likely, the 'hottest' kind of data you might find is someone accidentally leaking info akin to the World of Tanks forum post 'corrections'.
