whoever it is dosent seem to be doing anything for profit. im usually the vulture that picks over the remains in the area and takes everything that can be lifted, and i walk onto plots filled with corpses and animal corpses full of high quality stuff. one time i found a cupboard literally full with q150+ antlers. the most recent one had several cupboards full of q120+ meats of various kind, q70 treeplanter pots, a q50 butter churn (seriously, who the hell walks by a q50 anything made of wood and says "meh, i dont want that"), several dozen barrels full of milk and q60 flour, etc.
so yeah. just be careful, because someone in aki is a group full of pure asshats only here to ruin other peoples fun. i suggest extreme aggression to anyone wandering around outside your gates. maybe leave some scattered corpses outside so they know not to stick around.
This is what the mandatory combat alts are for.
Also, as of lately, most of the village can go 'meh' to q50 things. With no effort involved, most of us can produce q100 equipment, food, bricks, or whatever. I personalty leave stockpiles of q57 boards that I cut out of q10 logs just as basic building material.
Thanks for the warnings though, we will be sure to keep an eye out for any suspicious activity.
