This might explain somthing, as this picture is near a giant mushroom and they are picking blocks up, and Jeb's NPC village picture is near a giant mushroom aswell...

I think...instead of dismantling your structures, they build their own at night. Given enough time, they might make some sort of fortress. I dunno, looks like they're working on something...
You were too blind to notice that there is a bit of a scary thing.. they can lift water, in the image there are some random water spouts on the sides of the mushroom
my theory is that their minions of herobrine who steal and desroy [blocks] from your houses and bring them back to him so he can make a giant fortress and an army to destroy you
1: A Shadow/ Shadow person
2: Mutated Squid
3: A Demon
4: Tenticle Monster
5: And so on.
What it can do with those blocks could be:
1: It will steal blocks and run away (maybe that you placed?)
2: Smashes blocks/ Smashes blocks and throws it at you?
3: Creates Building/ Structures.
4: (wild theory) Steals Stuff out of your chests, your diamonds are never safe.
5: So on.
Any Other Ideas?

I tried it with terrible results. I gave my wife my glasses for a second, a creeper showed up and now my wife is pregnant.
Stupid 3D..
