1 In essence yes but in reality no. If people would seriously put out a concentrated effort it could be taken care of. People would rather just say ach they are crazy and get away with doing nothing. You still will have those people that seriously mentally snapped when the rebbe passed away.
2 Oh that. It wasn’t to kick anyone out, it was to decide who was in charge or rather if there was an official person who had a say over 770. It was renewed and the gaboim/rabonim won. Why they won’t/don’t kick the tzfati out I don’t know. Very likely because they don’t want to cause more problems than they already have.
