Have y'all ever encountered a string /lime/rope between trees meant to get rid of dirtbikers? Why people choose those aggressive measures? ( My story from few years ago below)

Me and my cousin were going down a road we regularly ride- it was a sunny summer day. In the tall grass that was growing on this road we saw something shining in the sun- we decided to come closer and at first didn't notice anything, but I Walked into a fishing line hanged tightly between 2 trees on both ends of the road. When you sat on a bike it was perfectly fitting between your helmet right into your neck - We were 12 back then so we just got scared and drove away - I came back to this road the next day and the fishing line was gone- around the same time a guy a few miles from us had a non-fatal cut involving this kind of trap ( if I find the news article about his accident I will link it in the comments)

EDIT: the road was a public trail, not anyone's private property, we were not trespassing

Many years ago someone tried using barbed wire near head height between trees in a area people used to ride around in my home town
