Best Practices for Responsible Data Collection on Telegram
If you need data from Telegram, stick to ethical and legal methods:
Utilize Official APIs ONLY: This is the safest and most sustainable approach.
Develop or use bots that interact via the Telegram Bot API.
Ensure your bot's behavior aligns with Telegram's ToS and rate limits.
Obtain Explicit Consent: If collecting any personal data through your bot (e.g., email, phone number, specific preferences), ensure clear, informed, and revocable consent.
Focus on Aggregated/Anonymized Data: For group analytics, focus on aggregated, anonymized trends and patterns of public conversations, rather than individual profiles.
