I was gathering some info on servers that have 33-34 max players.
Top of the list was SourceOP.

So I typed: connect 67.228.59.146:27015;wait 200;status;wait 100;disconnect

I was promptly disconnected with this message
Disconnect: Cannot run commands before entering game.

What sort of exploit is this trying to prevent?

This is purely out of curiosity.
