You still missed the point. I give up.
I understand you don't want to join a league until you know who else is joining. 
I didn't think you meant it on a personal basis, but more that you were concerned that you might end up with automoving or early dropping (or even unskilled?) players.
players who automove or drop can (according to my suggestion) be exluded
You could add a 'must have won 5+X games' (rather than just finished 5+X games in the last 30 days)- then you would get higher skill requirements too.
If you're worried on a personal level (for example if for whatever reason you didn't want to play in a league I play in) then setting up invite only games or password protected games and not handing out the password to everyone would be the obvious solution.
What have I missed  - don't give up

 I think it may be that if you extend the number of games required that someone has to complete before they can join a league - they can do this by automoving. 
Hence the problem isn't cured just delayed a short while.
