Yeah whenever there is a merger of sites or especially forums lots of hings could fall through the cracks. Especially if majority owner isn't keen on the contest thing.
Site merger creates many problems, also when a forum is sold to new owner. Many people who are in between of paid posting demand for money and the old owners asks them to contact new owner and new owners says that he didn't start contest.
You should always be careful when doing posting contest or posting jobs because the owner can run away easily.Better know who the owner really is before doing such things.
