What are best practices for avoiding doxxing yourself (sharing identifying details)?

Doxxing yourself — inadvertently sharing details that allow others to identify who you are in real life — is one of the most common and underappreciated privacy risks on Reddit, because it rarely happens through a single obvious disclosure. It typically happens through the accumulation of details across multiple posts and comments over time, where each individual piece of information seems harmless but the combination narrows your identity to a small number of people or even a single individual. The first and most important practice is to audit the details you share before posting rather than after. Before writing a comment that mentions your city, your profession, your age range, a recent personal event, or a specific experience, ask yourself whether the combination of that detail with details you have already shared elsewhere on your profile creates an identifiable picture. A single comment mentioning "I'm a nurse in Portland" may feel safe, but combined with a previous post about a specific hospital event, a comment about your commute route, and a thread in your city's local subreddit, it may narrow your identity considerably. Using a username with no connection to your real identity on any other platform is foundational. Avoid using your name, location, employer, or any identifier that appears on your social media profiles or email addresses. Creating a separate Reddit account for more sensitive topics — rather than discussing everything under one account — further limits the aggregated profile that others can build from your posting history. Be cautious with photographs and screenshots. Images taken on smartphones embed location metadata in some cases, and photographs of identifiable environments — the view from your apartment, a recognizable local landmark — can narrow your location more than you might expect. Screenshots of conversations that include your real name, phone number, workplace, or other details should have that information obscured before posting. Avoid posting about workplace incidents, family disputes, or personal conflicts in enough detail to be recognizable to anyone who knows you.
