Exam-Calendar-Aware Scanning

New Editions Are at Highest Risk in Their First Days on the Market

Most pirated shares of a newly published test bank or mock-exam book enter circulation on Telegram channels/groups within the very first days after release. To catch this critical window, our system runs prioritized scanning that is aware of your publishing calendar.

Why It Matters for Publishers

The Real Scale of Test-Bank & Exam-Book Piracy

Publishers producing exam-prep material for high-stakes exams (in Turkey, LGS, YKS, and KPSS among them) face a spread speed unlike other content types.

48 Hours The average time it takes for a newly released test bank to be scanned and reach the first Telegram channels.
10K+ Members The membership some "publisher archive" channels reach — a single leak can instantly reach thousands.
Exam Season Pirated PDF sharing and search volume rise noticeably in the weeks approaching major exam dates.
Piracy Threat Architecture

Violation Types We Target in Your Exam-Prep Content

Piracy of printed publications spreads through its own distinct channels; we monitor each one separately.

Scanned Book PDF Sharing

A printed test bank, topic-review book, or mock exam being scanned page by page into a PDF and shared.

Telegram Channel/Group Archives

Detection of "publisher archive" channels and groups, organized by year and subject, reaching thousands of members.

Answer Key & Solution Booklet Leaks

The answer key/solution booklet being shared without authorization alongside the test book itself.

Pirated PDFs Sold as Paid Bundles

Some channels and groups market pirated content as paid "bundles" or "subscriptions."

Google Drive & File-Sharing Links

Large PDF archives distributed through Drive, Mega, and MediaFire links shared via Telegram.

Forum & WhatsApp Group Redirects

Scanning of posts in forums and WhatsApp groups that redirect to Telegram channels hosting pirated content.

Process

How It Works?

A standard process is followed from detection to reporting.

Scanning

Telegram channels/groups, file-sharing sites, and search engines are scanned continuously.

Verification

It is verified that the detected PDF constitutes a copyright infringement using page matching.

Notification

A copyright infringement notice is filed with the relevant platform or channel owner.

Follow-up

The process is tracked regularly until the content is removed.

About This Service

We detect and take down scanned PDF shares of your test banks, exam booklets, mock exams, and topic-review books — prepared for high-stakes exams (in Turkey, LGS, YKS, and KPSS among them) — as they circulate on Telegram channels/groups, file-sharing sites, and elsewhere on the internet. Our AI-powered page and text matching system verifies that the scanned content genuinely belongs to your publication before the takedown process begins.

As exam dates approach, the spread rate of pirated shares increases sharply; a newly released edition being scanned and shared within a few weeks of publication is a common problem. That's why our system is aware of your publishing calendar and automatically increases scanning frequency during these critical windows.
