How a third-party bot network weaponized Instagram's own enforcement architecture against an Indian MSME —
and how one researcher dismantled it across three jurisdictions in 18 days.

"We're sorry that we've got this wrong and that you weren't able to use Instagram for a while."
— Instagram / Meta Platforms, Inc., restoration notice, 12 June 2026
Restoration notice and written apology. Recipient address redacted. Verbatim text: evidence/INDEX.md → Restoration Correspondence.
A permanently disabled Instagram account — closed after identity verification, with no further appeal permitted — was restored in 18 days through a coordinated legal, technical, and security-research campaign. The campaign identified a novel attack vector in Instagram's enforcement architecture and reported it simultaneously to Meta's CLO, CISO, CIB Director, Head of Instagram, and the California Attorney General.
This repository documents every step: the attack mechanism, the evidentiary architecture, the multi-jurisdiction legal strategy, the responsible-disclosure methodology, and the outcome.

The category 三陪 (sānpéi) denotes companion/escort services in Chinese internet slang — an adult-adjacent category that trips Instagram's integrity classifiers at a lower threshold than ordinary commercial spam. A deliberate choice by the attack operator.

Critical flaw: the classifier cannot tell content the account holder authored or authorized from content a third party injected into the referral parameter.
Weaponizability — the attack requires:
- ❌ zero authentication
- ❌ zero account access
- ❌ zero conduct by the victim
- ✅ fully replicable against any Instagram handle, at scale
The account's own data archive (downloaded 25 May 2026, 13:58 UTC) contains the decisive fingerprint:
{
"profile_status_changes": [
{ "time": "May 25, 2026 4:52 am", "activation_type": "inactivate" },
{ "time": "May 25, 2026 4:52 am", "activation_type": "inactivate" },
{ "time": "May 25, 2026 4:52 am", "activation_type": "inactivate" }
]
}Three identical events at the same timestamp. Manual enforcement produces a single event. Three simultaneous identical inactivate events are the signature of an automated threshold crossing — multiple contaminated classifier signals firing at once. The suspension email arrived ~8 hours later. The account holder had no knowledge of the attack.

Six simultaneous channels, all cross-referencing, all traceable through Meta's own systems.

The bug-bounty number was the skeleton key — every email, form, and filing that could carry
#2428878307595078did, so any Meta employee on any channel could pull the full technical record from their own system instantly. The California AG CC on the same email as 8 executives created cross-jurisdictional accountability no single channel could achieve.

📄 Full chronology: TIMELINE.md
- The
__d=attack surface is real and replicable. Any Instagram account can be targeted. The attack leaves no trace on the victim account and is indistinguishable from genuine integrity violations without forensic archive analysis. - Account data archives are forensic gold. Downloading your archive at the moment of anomalous activity captures the timestamped classifier signals that reconstruct the attack chain. The three simultaneous
inactivateevents were decisive. - Responsible-disclosure posture changes everything. Filing through the bug-bounty channel alongside legal channels repositioned the campaign from complainant to researcher.
- Multi-jurisdiction pressure beats single-channel appeals. The California AG CC alongside 8 Meta executives created accountability no individual channel could.
- Document everything. Notarize what matters. A notarized record filed under Indian law — affidavit, attested exhibits, Special Power of Attorney — signals a seriousness automated routing cannot ignore.

Chandandeep Sharma Authorized Representative — Dark Wolf India (UDYAM-CH-01-0045213)
This campaign was executed entirely independently — no law firm, no security consultancy, no institutional support. The methodology combined real-time OSINT, multi-jurisdiction legal drafting, security research and responsible disclosure, notarized evidentiary architecture, and strategic executive escalation.
This is believed to be the first documented case in India of __d= referral parameter injection identified as an attribution-poisoning attack vector against Instagram's integrity classifier, with simultaneous responsible disclosure through legal, regulatory, and security-research channels to Meta's senior leadership.
Bug Bounty Report #2428878307595078 remains open.
