Stop complaining. You wanted this.

Players, 1 chance per player.
Bot farms, 10,000 chances, due to bulk purchasing subscription time with stolen credit card numbers.

Wonder who wins.

Then they just sell the character, with the house, the person buys the character, a rename and a fantasia, and squenix makes money from it.

The only real deterrent I can see against bots spamming it is the requirement to put the gil up front (probably not an issue for a botter) and the requirement to be a 2nd lieutenant in your FC to be able to purchase it. Not sure if bots do the FC things and I don't think boosting caps your FC rank either, so some little effort has to be put into that at least.
