If I would experience an exploit, I would report it to the security team of the exchange, because I believe if you do the right thing, you get the same back from life.
How would the information change your "morals" if the exchange intentionally stole money from its users?
Well, people does have different minds which means people could decide neither they would abuse it out or would report or do the right way.
How would you change your mind if you knew that an infamous scammer used the same exchange and you had the chance to take back the money?
