A other possibility would be a player site in wich all players of seiv could get listed and when they play a game antil to finish they could get for example 5 points/an GM could get 10/and an replacement player maybe 6 points in that way
everyone who is an reliable player would be known to all others.
The points should not indicate how good or bad someone plays but thay should just be there so that it would be more harder for some others to join a game than to withdraw without reason and then sign up under a other name at seiv and then to harm the effort and fun of an other game and its players.
Of course when some one is new to seiv then who GM would chose him in his game without points ?Well a newcomer could get by sign up at seiv 5 points for example so that he also have a change to be selected for an game.
But unfortunaly to maintain something like that would be shurly to much work I guess.
I personaly try to keep the names of players who without reason drop away from my game and so i will not select tham should I start a new game but who hinders tham to sign up with a other name.
