The way this event was designed (with emphasis on RNG elements) directly encourages this kind of behavior, so I can't fault the players one bit for doing whatever they can to bring the RNG back in their favor. The only people that it's "hurting" are the people who don't care enough about maximizing their scores to follow suit and reenter, so chances are a good chunk of them don't even care anyway.
