The ability to stop people from buying you premium, via a button in the control panel.
Specifics/Details:
A button in the control panel, that you press, that when pressed, will stop the ability of other users to buy you premium. To be used by members of the site who may not wish to have $25 wasted on them because they plan to cut back on their use.
How this will benefit the site and/or other comments:
I for one have been bought premium 2 or 3 times. And while I have enjoyed it, my time at conquer club is coming to an end. If someone were to spend the $25 on me for premium again, it would just go to waste, I'd rather have the option of declining, so that the gift giver may give it to someone who would more happily enjoy it.
