What they're not telling you: # Reddit's Privacy Settings Prove Largely Cosmetic in Recently Discovered Workaround A simple browser modification can bypass Reddit's profile privacy settings, exposing supposedly hidden user data to anyone who knows the technique. According to a report from r/privacy, users believing their Reddit profiles are hidden from public view may be operating under a false sense of security. The workaround involves copying a profile URL, opening it in incognito mode, and replacing "www" with "old" in the address bar—a change that reportedly displays all content a user intended to conceal.
What the Documents Show
The poster claims to have tested the method on multiple hidden profiles with consistent results, suggesting this is not an isolated glitch but a systematic vulnerability in how Reddit implements its privacy controls. The discovery exposes a gap between what Reddit users think their privacy settings accomplish and what those settings actually do. When users mark their profiles as private, they operate on the reasonable assumption that their content becomes inaccessible to the general public. Reddit's interface supports this interpretation by hiding profiles behind privacy screens. However, the vulnerability suggests Reddit's old.reddit.com interface—a legacy version of the site maintained for users who prefer the older design—may not enforce the same privacy restrictions as the modern site.
Follow the Money
This creates a situation where a privacy feature functions as a speed bump rather than a barrier, deterring casual browsing while remaining transparent to anyone with basic technical knowledge. The broader implications extend beyond individual Reddit users. This type of vulnerability reflects a pattern across major platforms where privacy controls are inconsistently applied across different access points. Users grant trust to a company's stated privacy features without visibility into whether those features operate uniformly across all versions of the service. Reddit maintains multiple interfaces—new.reddit.com, old.reddit.com, the mobile app, and the API—each potentially with different permission structures. This fragmentation creates opportunities for privacy leakage that users cannot detect through normal use.
What Else We Know
What makes this particularly significant is that most users never consider that changing a URL prefix could circumvent their privacy choices. The discovery highlights how privacy on large platforms depends not on transparent, auditable systems but on security through obscurity—the hope that users won't discover workarounds rather than making workarounds impossible. This approach fails the moment someone documents the technique in a public forum, which has apparently already occurred. The incident also underscores why privacy cannot be treated as a checkbox feature. A user who discovers this vulnerability may reasonably question what other undocumented methods exist to access supposedly private information. If the "www" to "old" swap works, what about other URL variations, API endpoints, or cached versions?
