Private investigators are often called upon to investigate cases that involve social media. For example, harassment, fraud, hacked accounts, identity theft, catfishing, stalking, etc. It is important to understand social media networks to plan your social media surveillance efforts. Social networking websites allow you to connect and interact with a network of other people through personal websites, weblogs, online chat, photo sharing, discussion groups, and more.

Social Networking Services

A social network service focuses on building online communities of people who share interests and activities or are interested in exploring the interests and activities of others. Most social network services are web-based and provide a variety of ways for users to interact, such as e-mail, instant messaging services, blogs, photo sharing, and more. 

Social networking has encouraged new ways to communicate and share information. Social networking websites are being used regularly by millions of people worldwide. While it could be said that email and websites have most of the essential elements of social network services, the idea of proprietary encapsulated services has gained popularity.

The main types of social networking website services contain category divisions (such as former school year or classmates), means to connect with friends (usually with self-description pages), and a recommendation system.

Most of the companies on this list of social media network sites combine many of these functions, with Facebook widely used worldwide; MySpace, Twitter, and LinkedIn are the most widely used in North America; Nexopia (mainly in Canada); Bebo, Hi5, dol2day (mostly in Germany), Tagged, XING; Badoo and Skyrock in parts of Europe; Orkut, Friendster, Multiply, Wretch, Xiaonei and Cyworld in Asia and the Pacific Islands.  See below for a list of social networking website services.

Some attempts have been made to standardize these social networking services to avoid duplicating entries of friends and interests, but this has led to some concerns about privacy.

Facebook is the most popular company on this list of social media networks. Some consider Messenger its platform, but we consider it simply the messaging app for Facebook.


Google+ (discontinued) – Google+ makes connecting on the web more like connecting in the real world. Share your thoughts, links, and photos with the right circles. Use easy, spontaneous video chat to simultaneously start conversations with as many as nine people.

Hi5 – Headquartered in San Francisco, CA, hi5 is one of the world’s largest social networks. Alexa ranks hi5 as a top 20 website globally and the #1 social network in over 30 countries across Latin America, Europe, Asia, and Africa. hi5 is a globally diverse social networking site, with over 80% of our users from outside the US.

Mastodon – Mastodon is a decentralized, open-source social media platform that operates on a concept called “federation.” Unlike centralized social media platforms like Twitter or Facebook, where all users are part of a single network owned and controlled by a single company, Mastodon consists of multiple independent communities called “instances.” Each instance functions as a mini social network with its rules, themes, and user base.

MySpace – MySpace is an online social networking community that lets you meet your friends’ friends. Create a community on MySpace to share photos, journals, and interests with your growing network of mutual friends. MySpace has dropped considerably in popularity in recent years.

Tumblr – Tumblr is different than most other sites on this list. It allows users to establish and update a blog.

Twitter (more recently known as X) – A San Francisco, CA social networking website. People worldwide use Twitter to follow the sources most relevant to them and access information in real-time, as it happens – from breaking world news to updates from friends. In the past few years, the company struggled to demonstrate organic user growth, which led to disappointing earnings. The company is working to right the ship by introducing features like live streaming, expanded character limits, and more. We do not recommend using this social network.
