Forced obstacles by player

A lot of players in the new skate game place obstacles in front of ramps or common lines for people to hit it so, I think there should either be a setting or just by default; Everything should be disabled and you should have to walk up and enable it instead of the other way around. I feel like this would make the gameplay feel a lot smoother and not have as much player interference.

I do understand that this is a multiplayer game but people trying to sabotage this game gets repetitive and annoying. I think this is a common issue that has a simple solution.
