An idea I had for the site

So I have noticed a lot of people talking about the number of users entering each giveaway, as well as a good number of "hidden puzzle" private giveaways where if you solve the poster's puzzle you can enter the giveaway, so what about a system where the person posting the game could add a password or a phrase to their giveaway and to gain access you have to solve the puzzle. with this system you could see what is being given away ahead of time to see if you want to take the effort out and solve the puzzle as opposed to the current situation in the forums, this would also cut back on those types of forum post. This system could do other things as well for example instead of having a private like giveaway you could make it public and solving the puzzle lets the user enter the giveaway at a discount. So lemme know how terrible of an idea this is
