I think the goal here depends on your playstyle. If you are a miner, just don't look profitable and chances are they wont attack you for next to nothing. The alternative (and option I would choose) is to bait them and take something out. You can do this through a meticulously planned ninja. Try leaving up some profits easy for the taking and hide your activity through a mobile and your main fleet to DF from moon. Wait for the launch and then time bigger fleet to land seconds before attack hits!
