Item Drop Trolling

Seeing a lot of random items placed in the way of challenge lines. Like flatbars placed perpendicular to the line to make people bail, or quarter pipes placed backwards right the bottom of a ramp. A minor annoyance, but it happened like half a dozen times today on different challenges. 

I fully expected this, but I also expected EA to have a plan to combat it. I hate to say it, but items should be labeled with their owners name so trolls can be reported.
