the reason why the mods don't remove it is because they can't remove it. only the site administrator can, and he's too busy running the site. fluffly spells are last on his priorities list unless they pose a threat to someone.
while i would never cast his spell, theoretically it could work. you would be creating an energy being [not sure what the real title is] basically you can charge energy and create a being of energy which will look and act how you programmed it [because its your energy] once you stop feeding it energy, or wish to take the energy back, it will disperse.
depending on how good you are with energy work, it could be anywhere from one day, to a month [depending on how much energy you're feeding it] but this will not become a physical being. no spell can create a physical being from energy.
