Red Arrow

I was checking my game and I went out to the map and noticed a red arrow pointing towards my village. I got curios why and then I check by clicking on my village, I was actually got scouted. The crow did not inform me about it.
The problem of this game is this, you would not know who is currently scouting you, so you have to trace the origin of the line, took me around 15 minutes. And then I found out, the dude was 3 level higher than I am, so I have no chance of winning against him, what I did instead, I exhausted my resources to building troops, upgraded the most expensive building available and I did not claim my rewards yet so that when he check he would find nothing which will discourage him to still. And indeed he was discouraged. Hehehe.
