[OCCRA]: Question about dump station and goaltending

Is it legal for a member of your alliance team to put a trash can into a dumping mechanism and tilting the mechanism so that the opponent cannot score the bonus ball?

I believe this would count as preventing scoring, which is described as so.
“GOALTENDING: Blocking the TRASH CAN opening or any part of the DUMP STATION‘s volume that prevents an opponent from scoring”

So no, I don’t believe so.

So, just to be clear, in the last 30 seconds, if a trash can is left in the dump station tipped over, and just left that way to prevent the bounce ball from being placed there, that will be OK.

Just want to make sure I’m understanding this correctly.
