I'm not so sure tbh. Good strategies have a tendency to spread quickly anyway. Look at Korlock's siege on WI that suddenly became the standard almost, of which the siege of Oligarch was just a variation really.
I've never heard of that. In fact a good many of the new players have probably never heard of it either. Don't confuse personal experience with actual fact. There's no good reason to keep strategies for yourself in what's supposed to be a friendly game.
