How long do deleted games stay deleted
I'm not sure of the exact algorithm involved...but it depends on how long the game was active, how many posts were in it, etc...a game that never got off the ground goes away faster. (This may be how long a game sits inactive before it's marked for deletion, if the GM doesn't delete it on their own...I don't recall for sure.)
It also, if I recall correctly, depends on how long it takes someone at the moderator level to decide there are enough deleted games to go through and purge them...it's not an automatic thing.
