Reddit is a popular social media platform where users can share content and engage in discussions across a wide range of topics. It features diverse communities, known as subreddits, catering to specific interests and hobbies. Users can upvote or downvote posts and comments, influencing their visibility and prominence on the site. 

Researching on Reddit for OSINT purposes provides valuable insights due to its diverse user base and extensive range of communities discussing varied topics. Analysts can gather real-time updates, crowd-sourced information, and diverse viewpoints, aiding in understanding public sentiment, emerging trends, and niche subjects not widely covered by mainstream media. However, verifying the authenticity of information and discerning credible sources amidst anonymous user contributions remain critical challenges for effective OSINT on the platform. 

Researching Reddit without an account involves utilizing its public-facing features such as subreddit pages and search functions. Users can browse discussions, posts, and comments to gather information on specific topics. User profiles are also typically publicly available unless the profile has been made private or posts explicit content. Tools like third-party Reddit search engines and web scraping techniques can also be used to access archived content and track trends without the need for direct participation or account creation.

However, Reddit has recently been actively restricting access to its API (Application Programming Interface) for third-party apps. This move aims to exert more control over user data and improve platform security. As a result, many third-party Reddit apps have faced limitations or shutdowns, prompting users to rely more on Reddit’s official app and website for their browsing and interaction needs.
