Often times, a Spirit obsessor does not work alone. They often collaborate in their efforts to guarantee their success, whether their objectives are targeted toward a specific individual or group of individuals, or whether their aim is merely to spread discord, hate, and misery in revolt against their own unhappiness and suffering. They actually band together in groups analogous to "gangs" here on Earth. Spirit author, Manoel Philomeno De Miranda writes (in "Obsession"):

"Such entities- who eventually will be caught in the subtle nets of Divine Laws- build up vicious organizations in the Dark Regions of the Lower Planes from where they spread their influence throughout many places of suffering and perturbation on the Earth plane, attuning also to idle minds, and to guilty, stubborn, rebel, and indifferent persons. They establish a close relationship with these minds, starting serious, long, obsessive processes that sometimes last for a whole lifetime on the Earth plane, and continue in the Spirit World after the obsessed's death.

These inferior Earthbound entities organize themselves in bands and fight for leading positions as they would on the Earth plane, in actual battles in which they annihilate themselves. Their motivation is a powerful ambition which ends up in an empty ephemeral illusion. They lack the strength to control themselves but are always tormented by the lust for power.

Their evil, degraded minds, in molding the subtle tissues of their astral bodies, completely alter their appearance the better to frighten those submitted to them. In their insanity, they believe themselves to be small gods competing with the True God. Some of them still carry in their subconscious, the old religious myth of Hell and its Devils, and they mold their Spirit bodies to suit the thought forms they are firmly focused on."

Just like in gangs here on Earth, in these Spirit groups as well, there are those who give orders and those who follow orders. The same author also explains that the Spirits who gain positions of "power" in these organizations, also "obsess other discarnate entities like themselves, who in turn become obsessors of incarnate people, setting up a very complex circle of communal living, exploiting one another physically and psychically. They use these submissive fellow Spirits to intensify the persecution of their victims and the victim's family members, accompanying them day to day, seeking to cause them problems, emotional anxieties, confusion, etc., which they will achieve if this individual does not practice vigilance and defend himself with prayer and the reinforcement of virtuous thoughts and actions. The obsessive actions of Spirits, under the command of their "boss" and even sometimes in spite of their true, innermost desires to be free of such oppressive chains, is evident in the communications of Spirits who speak in mediumship sessions held for disobsession, when these entities give in to the persuasive and caring conversation of the counselor, stating that they would like to change but they can't because of the trouble they will be in with "the one in charge", and sometimes they fear not only trouble but also the loss of "protection" that they are given in exchange for their work (again, very analogous to the gangs we know on Earth). The counselor explains that they need not live in fear or in crime any longer, that they have come to the right place where they will receive true protection, shelter, and treatment that they need.
