I don't think that it's a scam attempt but everyone is just waiting to get paid and for the refill of the hot wallet. It should be filled within a couple of hours from now.
We don't like the delay that has been too long and everyone is experiencing inconvenience at that point. That's why it's why many are disappointed from that point.
I have to agree with you that scam might not be the appropriate term and Bitvest won't likely be turned into that.
But if that kind of action wherein everything is always a long delay, either in their campaign or to their user's withdrawal at their site, that was already unprofessional. Delays are ok and can't be avoided but if that's always the case for long, it's not good anymore and something needs to be done.
I hope the case will be properly addressed. They are one of the long-time running sites in the crypto-gambling community and the reputation built since then shouldn't be damaged.
