X Flags Brave Browser Users for ‘Inauthentic Behavior’ as Musk Says Platform Is Investigating
Brave browser users are reporting a surge of account restrictions, “inauthentic behavior” flags, and broken login flows on X, the social media platform owned by Elon Musk.
Musk replied “Looking into it” to a public complaint about the issue, confirming X is aware of the reports, though the platform has not released a formal explanation.
What Users Are Reporting
Affected users describe being locked out of accounts, hitting dead ends in X’s AI-driven appeals process, or encountering verification flows that fail to complete.
The appeals system has drawn particular frustration. Several users said the automated review process returned errors or provided no actionable path to restore access.
Brave CEO Brendan Eich responded directly to user complaints and pointed them to an active GitHub thread on Brave’s side tracking X login problems.
Eich also suggested X’s anti-bot systems may be generating false positives against privacy-focused browser configurations, and noted that at least one similar report had surfaced from a Firefox user.
Not Confirmed as a Brave-Specific Problem
Still, Brave has not been confirmed as the root cause. A separate set of complaints involves users who did not specify which browser they use, leaving the scope of the problem unclear.
The working theory — unverified by either company — is that X’s anti-abuse systems may be misreading signals from browsers that mask or alter standard fingerprinting data, the technical identifiers websites use to recognize returning visitors.
Privacy-focused browsers like Brave routinely suppress or spoof those signals to protect users, which could cause X’s automated systems to flag the behavior as suspicious.
That said, neither X nor Brave has published data confirming this mechanism is responsible.
A Pattern With Recent Precedent
This is not the first time X has caught real users in a wide anti-spam sweep. In March, a similar wave of account bans drew widespread complaints, and X later acknowledged that a spam-enforcement action had incorrectly targeted legitimate accounts — a finding covered at the time by PiunikaWeb.
In that earlier episode, reports were not tied to any specific browser or platform configuration.
By contrast, the current wave has drawn focused attention on Brave, in part because of Eich’s public engagement with affected users and the existence of a dedicated Brave GitHub tracking thread.
X has not said whether its anti-bot systems have changed since March, or whether any recent update triggered the new round of flags.
Brave, launched in 2016 by Eich — who previously co-founded Mozilla and created the JavaScript programming language — built its business model around blocking ads and trackers by default, configurations that set it apart from mainstream browsers such as Chrome and Safari.
That architecture, while popular among privacy-conscious users, places it in potential conflict with platforms that rely on behavioral signals for security enforcement.
