Legend, You have to know that with the new rules, Jail becomes repetitious and boring. The maps are more geared toward old style jail, (Syntax, Prison_Break, Etc.) They have very few in map games and nonmap based games or very limited.
There is two options to bring back the majority of jail players, Either obtain new maps from outside sources, as eGO's current map makers have retired, or are on break. (Captain Nighthawk, Rogue, and Christy.)
The second option is to lessen on the rules to what it was in mid 2010 and back. Rules are to the point as to where jail is giving to much of a equal chance to every Terrorist. Jail games are meant to kill off Ts, no matter if its fair or not. (I see this as a form of a handicap for less skilled or new players.)
The rules often drive away new players to our jail, seeing it as to much of a burden. Recently, new players have become warden and are trying games such as Russian Roulette, Trivia, and the sorts. To my dismay, they are informed of the jail rules and immediately leave, driving away potential players and recruits.
If things continue as they are, Jail will continue to lose interest and players will stop joining the server. This can be seen as : Jail used to be full when we still had the old style BlackOps, Now jail has not been full since late 2010. (This is to my knowledge) {NOTE : Yes I know the old BlackOps had a hack based into the map, but the new eGO version removes way to much from the map, making it unfit for our server.}
