if no one paid - I dont think the game would be here - some does pay something - and I am one of them.
I compare this to going to the Movies or watching a play in the Theatre. If they cant show any play or movie - they tent to inform the waiting audience - even if it is a free show - and they normally pay the money back also.
I cant see that it would be that big a deal for BB to give just the amount of gems we normally get from a weeks login bonus - maybe 50 extra to get peoples spirit up - and maybe a day extra prem.
