Lol, you have 36 square kilometers to explore. Since you can only see about houndred meters in any direction, you could run for 180 km before exploring all of the available area. It is beyond me why you STILL complain about borderguard. I've also said that I'll probably expand the area if you explore all of the map, but if it results in you running around and exploring everything SIMPLY to make me expand it, I won't.
A few months ago there were no problems. We were fine exploring within approx 2 km from spawn from April all the way to September, and we found many awesome landscapes within that area. You only started on this sillyness after 1.8 came out.
Just ignore borderguard and play like you normally do. When you hit the border, turn right or left or around.
If you don't stop this ridiculous complaining, maybe I should adjust the borders down to 2 km when the full game is out. So you will finally be happy when I expand it back to 3. *Evil kolling*
