Normally put on some wiz-bang starship or advanced technology that you rather have destroyed than to have fall into the enemies hands. Of course, purposely hitting this and then flying your ship into your enemies hands might work just as well.

I think one of these needs to be added into everything2's code. You know, when you write something so completely off-topic, offensive, wrong, and with bad spelling (because you've had no sleep for 60 hours, and the caffeine started making your fingers spasm) you can save the editors a step by nuking your own node while saving yourself from the swarms of downvotes headed your way.
