I'm simply reiterating what has been stated before. That when attacked you have the option to fight, pay the attacker to leave or log off which I "believe" includes paying them but I don't know for sure on the third option. If you leave for a week the peasants will be busy till you fill up your storeroom but not much will happen beyond that. (At least going by current info) I suppose they could add meteor showers later on
Read the FAQs slowly and you'll discover most answers. It may take a couple of readings though. There's a ton of info in there.
