Bans on WhatsApp Brazil

Understand the Crisis and How to Protect Your Business

The year 2025 marked a critical period for Brazilian users and businesses that rely on WhatsApp. A sudden and massive increase in account bans — many of them apparently unjustified — caused significant losses and exposed the vulnerabilities of those operating outside the platform's official guidelines. This article analyzes the multifactorial causes of this crisis and presents a strategic solution: using the Official WhatsApp API through certified platforms like SprintHub, which offers robust protection against bans while enhancing business communication capabilities.

The Anatomy of the Crisis: Why Were So Many Accounts Banned?

1. WhatsApp's Official Policy: Increasing Rigor

WhatsApp has an explicit ban policy for accounts that violate its Terms of Service. The main infractions include:

• Use of unofficial apps: These modified apps represent security risks not validated by Meta

• Illegal data collection (scraping): Extracting user information without authorization

• Spam and mass messaging: Unsolicited sending of large volumes of messages

• Illegal content: Dissemination of fake news, threats, scams and malware

In 2024-2025, Meta significantly intensified enforcement of these rules, making its detection algorithms more sensitive to suspicious behavior patterns.

2. The Technical Trigger: SORVEPOTEL Malware

The event that triggered the massive wave of bans in October 2025 was the spread of the self-propagating malware SORVEPOTEL (also known as Water Saci).

How the attack worked:

1. Initial vector: Victim receives a WhatsApp message from a compromised contact (appearing legitimate)

2. Malicious attachment: ZIP file disguised as a common document (receipt, quote)

3. Specific target: Messages instructed opening on a computer (WhatsApp Web)

4. Infection: Malicious script installed the malware on Windows

5. Account takeover: The malware took control of the WhatsApp Web session

6. Self-propagation: It automatically sent the malicious file to all contacts and groups

The devastating result: Legitimate user and business accounts, once infected, began to send massive spam involuntarily, triggering WhatsApp's anti-spam systems and resulting in almost instant automatic bans.

This scenario created a cruel paradox: the victim of the cyberattack was treated as the perpetrator of the violation. WhatsApp's algorithms, based on behavioral analysis, could not distinguish the user's intention — they only detected spam and banned the account.

3. Algorithmic Hardening: The New Anti-Spam Era

Alongside the malware outbreak, Meta implemented systemic changes in its policies:

New anti-spam mechanics (2024-2025):

• Counting of unanswered messages: System began limiting messages sent to contacts who do not respond within a monthly period

• Alert system: Notifications when the user approaches the limit

• Focus on high volume: Rules targeted especially at commercial accounts and mass broadcasts

Factors that began to drastically increase the risk of ban:

• Sending messages to a large number of unique recipients

• Use of financial keywords ("PIX", "boleto") in unilateral messages

• Launching campaigns from newly activated numbers

• Low response rates in commercial communications

4. Global Context: 6.8 Million Accounts Blocked

In the first half of 2025, Meta blocked 6.8 million accounts linked to fraud, most originating in Southeast Asia. These criminal networks use increasingly sophisticated tactics, including:

• Artificial Intelligence (ChatGPT) to create convincing scam messages

• Advanced social engineering techniques

• Mass cloning of accounts

• Coordinated disinformation operations

This external pressure forced Meta to adopt a zero-tolerance stance, whose side effects were felt by all users, including legitimate ones.

The User Experience: An Opaque and Punitive System

The "Banned Out of Nowhere" Phenomenon

Reports on social networks and specialized forums reveal a consistent pattern of frustrations:

• Sudden bans with generic justification of "violation of terms of use"

• Lack of transparency: Platform does not specify which rule was breached

• Ineffective appeal process: Reviews result in almost instant rejection

• Automated system: Perception that there is no contextual human analysis

• "Flagged" accounts: Even after recovery, accounts remain susceptible to new bans

Algorithmic Anxiety

The combination of opaque rules and severe sanctions created a climate of "algorithmic anxiety":

• Users banned in 2025 for messaging patterns they had maintained for years

• Fear that normal actions (use of VPN, switching between devices, messages to unsaved contacts) may trigger algorithms

• Self-censorship and limitation of use for fear of losing the main communication tool

The Legal Battlefield: Brazil vs. Meta

Brazilian Justice as Court of Appeal

Facing the ineffectiveness of the internal process, Brazilian courts became, in practice, the final instance of appeal:

Landmark case (TJCE, 2025):

• Meta ordered to pay R$ 10,000 in moral damages

• Court recognized WhatsApp as "essential in interpersonal and business communication"

• Decision framed unjustified ban as a failure in the provision of an essential service under the Consumer Protection Code

Threats of National Suspension

In Goiás, a judge threatened to order the suspension of WhatsApp across the national territory due to failure to comply with an order to reactivate a WhatsApp Business user's account. Although not enforced, the threat demonstrates:

• Low tolerance of Brazilian courts with tech giants

• Potential for localized disputes to escalate into national crises

• Conflict between Meta's global policies and sovereign Brazilian legislation

Jurisdictional Clash

On one side: Meta's model based on global Terms of Service applied by automated systems

On the other: Brazilian legal framework centered on individual rights and consumer protection

Brazilian courts are effectively asserting the primacy of local legislation over the contractual terms of a foreign company, treating access to WhatsApp as a consumer right, not a corporate privilege.

Disproportionate Impact in Brazil

WhatsApp as Critical Infrastructure

In Brazil, WhatsApp transcended its role as a messaging app to become critical commercial infrastructure for millions of small and medium-sized businesses (SMEs):

• 169 million Brazilian users (practically the entire connected population)

• Primary customer service channel

• Sales and marketing platform

• Essential tool for operational coordination

The SME Dilemma

The stricter new policies create a dilemma for Brazilian companies:

Common business practices that are now risky:

• Sending catalogs and promotions to existing customers with low response rates

• Marketing campaigns via broadcast lists

• Commercial communications from new numbers

Result: A global policy decision made in Menlo Park has the effect of stifling the entrepreneurial activity the platform helped to flourish in Brazil, creating a new class of "accidental spammers".

3. Regulatory pressure: Global lawmakers push for more transparency and due process

4. Malware evolution: Threats like SORVEPOTEL will continue to evolve

Brazilian Scenario

1. Growing judicialization: More actions against Meta in Brazilian courts

2. Possible specific regulation: Brazil may legislate on moderation of essential platforms

3. Migration to API: Serious companies will migrate to official channels out of necessity for survival

4. Market consolidation: Official Meta partners like SprintHub will gain prominence

Conclusion: The Choice Between Risk and Resilience

The sudden increase in bans on WhatsApp Brazil in 2025 was not an isolated accident, but rather the confluence of multiple crises:

1. Technical crisis: The SORVEPOTEL malware outbreak turned legitimate users into spam vectors

2. Policy crisis: Meta's algorithmic hardening created a punitive and opaque environment

3. Fraud crisis: Global increase in criminal activities forced zero tolerance

4. Governance crisis: Clash between automated global policies and local expectations of justice

For Brazilian companies that depend on WhatsApp, the choice is clear:

❌ Continuing with the conventional WhatsApp Business App = Operating in a permanent risk zone, vulnerable to arbitrary bans, malware and unpredictable algorithmic changes.

✅ Migrating to SprintHub with the Official WhatsApp API = Ensure full compliance, eliminate technical vulnerabilities, obtain institutional protection from a certified Meta partner and enhance operations with world-class CRM and AI.

The question is not IF your company will be affected by the next wave of bans or the next malware attack. The question is WHEN — and whether you will be prepared.
