Oh, ok, then that's part of the bigger problem of Counter-revolutionary processes, though it's a wider term that can apply to anything that slightly deviates from the goals of the person employing it, including more "radical" or more "anarchistic" movements, it was first used for people opposing the french revolution and trying to reestablish monarchy. It's not a specificity of anarchism, more of any revolution. I'm afraid there is no clear answer to that problem, it will always depend on local specificity and have an at best imperfect solution.
