Need advice: static imploding because of cheater.

Tell the people still in your leaking static that you're gonna continue recruiting. Give them chance to leave if they so will, but also tell them you'd like to keep them if they can wait. Communication is the key.

It's no use to hang on people if they are doubtful an kinda want to leave. Recruit your new people and try create team spirit you all share. You need to share the objective, or the group will keep on failing.
It won't be cakewalk, but to build static to last you're gonna have to put in work as a static leader. I myself always preferred to call myself management and maintenance (for static).

Last static I lead was for e1s-e8s. I dispersed us when it became clear that people had begun to want different things by e9s. some wanted to get into midcore/hardcore intensity, some wanted to keep on doing it pretty casual. all i could do, and i did it happily, was to make sure that everyone left with best preparations to find a new static, aka BiS gotten.
