Botters in your large FC ?

Yes they do you just need to touch three, not harvest them. But like others said you have to touch three, so it's more a case of are you sure you didnt see them touching three close nodes since you dont see the same nodes someone else sees. You only double a node together half the time.

So long as you don't actually act with the node (And it's not an unspoiled), you can certainly run between nodes and they'll stay spawned. Until you deplete them, they don't change. Just to verify, I tested in Mor Dhona on the level 50 deposits. Right click on the node, then just close it. It's still there. Run to the next node, harvest one item (A map on the first node, a shard on the second node) then exit. The node's 'health bar' is down a notch, but it's still active. So long as you don't deplete them, they stay there.
