I don't really see the overall point of this rule. The claim that using it to intentionally to block bullets stops it from being prop abuse makes little sense as people intentionally pick up props to kill, fly etc all the time. Plus I can see a bunch of people making mistakes like picking it up in a hurry and flinging it into someones face and killing them. Or someone pushing another player off an edge trying to block shots. I just personally feel it does more harm than good. Plus in my experience prop abuse happens more intentionally than non-intentionally. For example you don't just accidentally prop fly or walk around the map flinging minecarts at people.
