To stop throwing the balls back over the fence?

[Danielsss]

Those bloody balls. The kids next door constantly play ball games, the balls always go over our fence! We would always get a knock on the door, every 2 minutes. I ended up saying if just throw it back over, it's still as frequent!!! How do I stop this?

I don't live in the place in the photo (it's a National Trust property); I'm out of England for work.

Hopefully I won't return home to find the concrete littered with the squashed children, yet more valiant foot soldiers in the war against ball-stealing Trunchballs.

If you're concerned about trolling, do report.
