For many users in Hong Kong, a notification from WhatsApp is usually a sign of a family update or a business coordination. But recently, a different kind of message has been proliferating across the digital landscape: unsolicited offers for “direct push” marketing services, promising “first-hand sources” and mass distribution of digital business cards. These offers, often laundered through social media platforms like X (formerly Twitter), point users toward encrypted Telegram handles to finalize deals.
A recent surge in posts on X, such as those promoting services by operators like “Da Hong” (@dhch2626.yqg), highlights a sophisticated shadow economy of grey-market digital advertising. By bypassing official Meta advertising channels, these operators offer businesses a way to inject promotional content directly into the private inboxes of thousands of targeted users in the Hong Kong market. While the pitch is efficiency and reach, the reality is a complex web of bot farms, scraped data and systemic violations of platform terms of service.
As a former software engineer, I recognize the architecture behind these operations. They typically rely on “WhatsApp mods” or unofficial APIs that automate the sending process, paired with vast databases of phone numbers harvested from leaked directories or web-scraping tools. For the business owner, it looks like a shortcut to growth. for the end user, It’s a persistent breach of privacy that turns a personal communication tool into a billboard for unsolicited spam.
The Mechanics of the ‘Grey Market’ Push
The services advertised on X as “WhatsApp ad distribution” (广告代发) do not use the official WhatsApp Business API, which requires a rigorous verification process and adheres to strict opt-in rules. Instead, these operators utilize “bot farms”—clusters of virtual phone numbers and automated scripts—to blast messages to lists of numbers that have never consented to be contacted.
This “direct push” strategy is designed to create an illusion of intimacy. Because the message arrives in a chat thread rather than a traditional ad banner, users are more likely to open it. These campaigns often promote high-risk or unregulated industries, including offshore gambling, unregulated financial schemes, and “grey” e-commerce, which are frequently banned from official advertising platforms like Meta or Google.
The transition from X to Telegram is a deliberate security measure for the operators. By moving the transaction to Telegram, they leverage the platform’s high degree of anonymity and lax moderation, making it nearly impossible for authorities or Meta’s security teams to trace the origin of the spam campaigns or the identity of the service providers.
Why Hong Kong is a Primary Target
Hong Kong represents a strategic nexus for these operators for several reasons. First, WhatsApp is the dominant communication tool in the region, used for everything from casual socializing to high-stakes corporate deal-making. This high penetration rate ensures that a “direct push” campaign has a massive potential audience.
Second, Hong Kong serves as a critical gateway for mainland Chinese businesses seeking to enter international markets. Many of these businesses operate in a regulatory grey area and find official advertising channels too restrictive. The promise of “first-hand sources” (一手货源) suggests that these operators provide not just the delivery mechanism, but also the leads—pre-filtered lists of high-net-worth individuals or specific professional demographics within the city.
Official vs. Grey Market Distribution
The difference between legitimate business communication and these shadow services is stark, particularly regarding data provenance and platform stability.
| Feature | Official Business API | Grey Market ‘Direct Push’ |
|---|---|---|
| User Consent | Strict Opt-in Required | Unsolicited/Scraped Lists |
| Account Risk | Low (Verified) | High (Frequent Bans) |
| Delivery Method | Approved Templates | Automated Bot Scripts |
| Compliance | GDPR/PDPO Compliant | High Privacy Risk |
The Legal and Security Fallout
For the users receiving these messages, the risk extends beyond mere annoyance. Many of these “business card” promotions are precursors to phishing attacks. Once a user engages with the bot or clicks a link, they may be directed to fraudulent websites designed to steal credentials or install malware on their device.
From a regulatory standpoint, these practices likely run afoul of Hong Kong’s Personal Data (Privacy) Ordinance (PDPO). The ordinance generally prohibits the use of personal data for direct marketing without the data subject’s consent. When operators scrape numbers from the web or buy them from “sources,” they are operating in direct violation of these privacy protections.
Meta has intensified its crackdown on unofficial API usage. The platform uses machine learning to detect patterns typical of bot farms—such as sending hundreds of identical messages to non-contacts in a short window. This often results in “permanent bans” for the accounts involved, leading the grey-market operators to constantly rotate through new virtual numbers, creating a perpetual game of cat-and-mouse with the platform’s security algorithms.

The Path Toward Platform Integrity
The proliferation of these services indicates a persistent gap in how encrypted messaging platforms handle the tension between user privacy and spam prevention. Because WhatsApp is end-to-end encrypted, the company cannot see the content of the messages to filter them in real-time; instead, it must rely on metadata and user reports to identify awful actors.
The next critical checkpoint in this struggle will be the continued rollout of Meta’s enhanced account verification and the potential integration of more robust “spam reporting” tools that can trigger faster, systemic bans across linked bot networks. As Hong Kong continues to tighten its digital privacy enforcement, the window for these unregulated “direct push” services is likely to narrow, forcing operators further into the fringes of the dark web.
