Circumvention via adult identities cannot be fully eliminated

What it is

Real-name systems face continuous adversarial pressure from identity misuse: minors completing verification with a parent's identity, registering on a grandparent's account, or asking an adult to pass face verification for them. Such circumvention cannot be fully eliminated—verification establishes that the identity information is real, not that the person using the account is that identity, and the system cannot judge that correspondence inside a household. Acknowledging the ceiling is not abandoning protection; it means restructuring protection from "a single verification gate" to a layered structure of "verification + behavioural signals + family tools."

Why it happens

Circumvention's root is the verification mechanism's structural gap: identity verification binds "account to identity," while protection needs to identify "the actual player at the moment of use," and the gap between the two is the circumvention space. In-household misuse is nearly undetectable (with parental cooperation the system cannot distinguish), while social circumvention (borrowing an adult's identity to register) can be partially detected through behavioural signals: deep-night sessions, spending patterns inconsistent with the claimed age, usage profiles overlapping known minor patterns. Behavioural detection has a ceiling—misjudging adults as minors (false positives) and missing well-camouflaged minors (false negatives) are two sides of one threshold, and behaviour profiles themselves carry bias risk (treating certain play-style features as minor signals). More fundamentally it is adversarial: once detection rules are understood, circumvention adapts to them—a continuous cat-and-mouse relation, not a one-time engineering fix.

Where it stops holding

"Cannot be fully eliminated" does not mean "not worth trying." Detection and countermeasures work by raising circumvention cost: face verification raises the cost of borrowing identities, behavioural detection raises the exposure risk of long-term misuse, and cost increases prevent some circumvention entirely. False-positive costs must be taken seriously—an adult misjudged as a minor (with playtime and spending restricted) suffers real harm, so appeals and rapid-recovery channels are mandatory components of the detection system. Legitimate in-family proxy operations (a parent completing face verification for a child) and malicious evasion (a minor stealing a parent's identity) are behaviourally indistinguishable; this grey zone ultimately depends on family education, not technical adjudication. Regulators' realistic stance also acknowledges the ceiling: the legal requirement is "reasonable measures," not "guaranteed zero circumvention," and the design target should be set accordingly.

Applying it

• Layer detection: a verification gate (real-name plus face) + behavioural signals (unusual hours, spending, play patterns) + family tools (guardians see anomalous logins and spending)—each layer bypassable alone, but the combination raises cost substantially.
• Give misjudged adults a fast appeal and recovery channel (face re-verification, human review with a committed turnaround) to minimise false-positive harm.
• Verification: backtest detection rules against known circumvention cases (confirmed through support contacts), measuring hit rate and false-positive rate. The balance point of the two sets the trigger threshold, which needs periodic recalibration as circumvention behaviour evolves.
