Check in the campaign thread that over 25 users applied before he announced that the campaign is starting in 5 days. Now, for the next 5 days, they won't even know if they're accepted or not, and they'll advertise 1xbit for free.
like I said it will be up to the participants if they are willing to take the risk, wait, and advertise 1xbit for free for the next remaining days before the signature campaign resumes. besides, there's really nothing you(or I) can do and they are also not the first signature campaign that has done similar things like this(at least as far as I remember).
