I haven't tried to pillage with any of them yet, but that may only be a matter of time... I know that if you park one inside another civs border, the other civ warns you to remove your troops. With the explorer this does not happen (unless you're at war with that civ anyway)...

Well.. the AI can ask you to remove explorers, but will never give you the <your troops will move automatically> prompt. They don't care that much. That said, you can station your explorers on all their strategic and lux resources and pillage them on the first turn of war. Or you can just send the explorer over before that resource is improved and sit on top of it so the AI can never use it. Both are dirty, but hey... who cares, screw the AI

Your rep will take a hit.

I have used this strategy in the past and they can be killed by barbs. Also, I have had an AI declare war on me by attacking one who was scouting outside their borders.
