There could be an unpredictable reasons behind this, but all I could remember for some few months was the intention of the campaign manager to see the management team come to the conclusion of expanding the campaign to be able to take in more new participants, it may also be as a result of some lite maintenance the site might have been going through currently or later to be into effect, i want to believe that the statement being pause for the time being is giving a probability of returning back since it's not ended.
