Really, why do you have to do this?
What makes you think that a user doesn't need the $5 they are making each month from activeDen anymore? Yes, I really mean the importance of $5 each MONTH, it's not a misspelling...
$5 in a month matters much in some countries, and now you're cutting it from your users.
Only An Example: You can buy aprox. 30 (thirty) KILOS of RICE with $5 ($1 = 6 KILOS OF RICE), in Cambodia (true story) - Can you imagine that how many people would be feeded with $5?
Does ActiveDen a hunchback that big on your back?
