Then I discovered each new target face would indeed develop these black holes and not necessarily in the same place. I started healing the target face and found that you can get a black hole to grow right in the heart of the spot. The problem is that some tournaments don't allow the healing of the holes. On occasion, at outdoor tournaments, I find a black hole that is not in the spot. So in the end I've found that the national level spot-hogg was gracious and helpful.
Black holes do exist.
A black hole in the right place is to be enjoyed. The only defense I have against them in the wrong place is to not look at them. I am convinced that looking at black holes gives them power. Give all spots a quick death.
