Do you really want to know why? I'll tell you the secret answer.
They don't want to pay you. That's all the secret. They have paid user enough and Don't need new file upload too much. With all the files in their server, they can get money from new paid user for free. 4 month? think about $10,000 per month with no need to pay any cent and you will get it.
And when their revenue drop down, They can start their reward program again easily. They have huge number of user. They control this game.

Thats not true..they stopped the reward system because of the lawsuits that are being brought against the other filehosts who pay out. its a smart move for them.
