First, I will briefly introduce some major, contemporary criminology theories:
1) Space Transition Theory
Developed by Dr. K. Jaishankar, this theory has seven postulates. This theory aims to explore why cyber-crimes occur.
a) Cyber crimes are attractive to people with criminally repressed behaviors as they tend to remove the social judgment and disgrace physical-space crimes engender.
b) The anonymity factor in cyber crime further removes social stigma.
c) Cyber crimes are becoming more attractive to traditionally focused, organized crime groups due to the challenges of tracking such crimes by law enforcement.
d) The global, spatiotemporal (referring to space and time) nature of cybercrime renders advanced, criminal activity possible across wide domains.
e) Recruitment opportunities abound on the Internet, in the form of discussion forums, chat rooms, and other social media (such as Twitter and Facebook).
f) People from closed societies are more likely to commit cyber-crimes than people from open societies.
g) Conflict of norms and acceptable behavior between various cultures across such a wide, global domain, precipitates the rise in cyber-crime.
2) Routine Activities Theory
This theory focuses on crime prevention. It greatly highlights the element of opportunity in criminal acts. One of many theories associated with environmental criminology, routine activities theory is predicated on three elements:
a) Strong, influential persons in the lives of potential offenders aid in crime prevention. Influential persons are termed 'handlers' in Routine Activities Theory; handlers include teachers, parents, coaches, etc. Crimes take place when handlers are weak, corrupt, or ineffective.
b) Targets or victims with strong, influential guardians in their lives are less likely to fall prey to potential offenders. Guardians include police officers, security guards, parents, and teachers. Engaged guardians are able to track the focus and tone of interactions across social media.
c) Ineffective place managers lead to more crimes. In this theory, place managers are often merchants, property owners, motel clerks, recreation works, parking-lot attendants, and security guards. Weak, corrupt, or absent place managers lead to more crime. In the area of cyber-crime, effective place managers such as librarians, teachers, and parents track computer use in libraries, schools, and homes, in order to reduce pedophile and predator victimization of young children and teenagers.
3) Deterrence Theory, Social Learning Theory, and Self-Control Theory
Experts hypothesize that these theories are effective explanations for digital piracy. The rational choice theory states that every individual weighs the costs and benefits of his/her action to arrive at a rational choice for action.
Social learning theory states that behavior is learned by observation. Therefore, college students prone to engage in digital crimes tend to have already observed their fellow peers committing such crimes without consequences.
The self-control theory states that individuals with lower self-control commit more cyber crimes. As with routine activities theory, the self control theory explores the role of strong guardians in preventing digital piracy: less effective parental control (stemming from weaker emotional attachments with their offspring) incapacitates efforts to prevent digital piracy.

4) Neutralization Technique Theory
This theory states that offenders use denial-of-victim and denial-of-injury techniques to minimize guilt from their actions.
As you can see from the above examples of criminology theory (in the area of cyber crime), there is a seeming overlap between these theories. In all these theories, the concept of a strong and effective place manager/guardian/authority figure is a necessary aid against cyber-crime.
Another point to consider is that, the often sheer logistical and legal implications of tracking criminal activity across social media presents a challenge in crime prevention.
