We don't know what the concerns are exactly, so please refrain from jumping to conclusions until official word is out, as Froggy has stated that they cannot give out any information about what's happening behind the scenes yet, as much as they would like to.

It is not known when the game will reopen, as it will not be reopened until the developers are confident that the game is in a safe position.

Again, please refrain from jumping to conclusions and attacking any IP holders. The game is not gone, and will be back.
