i have no idea BUT chances are it was removed..or moved.
if people report stuff (something was offensive, copyrighted etc) it might get deleted. if you posted in the wrong spot it was maybe moved to a more appropriate spot.
i have no way of knowing what happened to your post specifically..but if it was removed it was probably for a reason. if it was only moved you can check your activity section and possibly find it.
