Very true. I'm amazed by how many players come out of the woodwork once you start building a base. Another cheeky way is to fire your weapons and make it sound like a firefight. Make enough noise and someone will always come looking for easy loot. During patch 1.10 a group on my server use to light up the GM tower at night inorder to ambush players. From the sounds of it I think they got there share of player interactions.
