It's probably more suitable to mark Coinroll as 'flux' rather than 'A'. They don't accept/reject participants immediately, but let everyone express their interest and will pick the best few in an unspecified time. So bit similar to Betcoin, which technically is always open but only for 'exceptional' posters and waiting list for others.
The situation is very similar to other campaigns, tbh. Lutpin and Gianluca doesn't reply at the same day users have shown their interest in joining the campaign. It actually takes days before they respond unlike SFR, yahoo, and Avirunes. Also, coinroll is partially being managed by yahoo so I think he's always on it when somebody shows interest in joining the coinroll campaign.
In addition, you won't actually know if yahoo or Namworld isn't actually accepting/rejecting participants immediately. Users will receive a PM from him or Namworld regarding the approval of the enrollment as stated in here:
