By the way, if you want to tell if your neighbors are truly inactive, one way is to watch their AW KP input. If they're at that stage and have built one, at least.
I've got one neighbor who has every wonder at Rune Phase - ten or so of them - and has done for more than a month. They're in an FS, so if they're giving to fellows' AWs, they should get runes occasionally - unless they never get the first couple of chests), and if they participate in tourney, the should get whole and broken shards - they can make a whole shard with ten broken ones. (I usually use mine for crafting, but there was that one time with the Mountain Halls....)
Of course, even then, it's entirely possible that they're just upping their fellows' AW KP and not bothering with their own because they're "on hiatus" and logging in maybe twice a day to throw the free 10 KP to a member of their FS.
