Telegram Android version empty account elimination techniques and batch cleaning plan

As a team that has been deeply involved in social media operations for a long time, we often encounter this problem: when sending group messages on Telegram, the list is mixed with a large number of invalid empty accounts, which not only wastes the push quota, but may also affect the health of the account. Especially when using Android devices, the official does not provide direct empty account filtering function. Do you encounter this problem? According to the DataReportal 2025 report, the average proportion of invalid contacts in global social media accounts is as high as 18%, which is a typical operational search demand.

Telegram Android version empty account detection principle

The problem of empty accounts is essentially the difference in the server's response to the account status. We have used packet capture tools to analyze and found that active accounts will return "last_online" timestamp, while empty accounts usually return "user_deleted" status code. Hootsuite's 2024 study noted that manually screening 1,000 contacts took an average of 47 minutes, which is why a systematic solution is needed.
