I find it interesting that people think rules can only be enforced by a position of power above the offender, rather than a consensus of their peers and equals.
Historical anarchists enforced their rules through a state apparatus that organized mob lynchings and targeted killings. The CNT-FAI and Ukrainian Free State both had secret police organizations, and the former was no stranger to political terror.
Indeed, all successful (even temporarily) anarchist groups grow a state apparatus.
Which is inherently fine, states are a tool of class warfare. The capitalist ruling class uses state power for its own ends, a successful worker ruling class needs to do the same.
