User Settings: Users have granular control over who can add them to groups or send them messages. Many users set their privacy settings to block unknown contacts, rendering scraped data useless for direct outreach.
In short, reliable and scalable scraping of actionable contact information from Telegram is either technically difficult, quickly thwarted, or outright impossible for most users.
The primary reasons to avoid scraping Telegram contacts are not technical, but ethical and legal:
Violation of Telegram's Terms of Service: Telegram's Terms of Service explicitly prohibit the use of its platform for spam, unsolicited messages, and the harvesting of user data without consent. Violations can lead to permanent account bans and legal action from Telegram.
Breach of Data Privacy Laws (GDPR, CCPA, etc.):
Lack of Consent: Scraping means collecting personal data sweden telegram mobile phone number list without the explicit, informed consent of the individual. This is a fundamental violation of virtually all modern data protection laws globally.
No Legitimate Basis: For most marketing activities, there is no "legitimate interest" or "contractual necessity" to justify the collection of data through scraping.
Right to Be Forgotten/Erasure: Even if you somehow collected data, you would have no legal basis to process or store it, and individuals have the right to request its deletion.
Data Minimization: Scraping indiscriminately collects data, violating the principle of data minimization (only collecting what's necessary).
Fines and Penalties: Violating data privacy laws can result in severe fines (e.g., millions of Euros under GDPR) and significant reputational damage. Local laws in Bangladesh are also evolving, and adhering to ethical data practices will become increasingly important for businesses operating there.
Spam and Unsolicited Messaging: Any attempt to use scraped contacts for direct marketing (e.g., adding them to groups without permission, sending unsolicited DMs) constitutes spam.
Negative User Experience: This creates an incredibly negative user experience, leading to immediate blocking, reporting, and a strong association of your brand with spam.
