Satoshi is doing a good job staying hidden and his probably one of the most hunted people on the net at the moment. It's not easy but it's possible as he has showed us.
The difference between satoshi and defcon is that defcon was active in the community he was participating in while satoshi left the community long before he was someone that people would want to dox
In fact the most useful piece of advice which would be marketplace operators should follow is to check their ego and be as invisible and behind the scenes as possible. Actively participating in "the community", and especially adopting the role of "visionary leader" is just plain stupid. It's an illegal business first and foremost. Leave the ideological bullshit to the users instead of courting their adoration.
