Telegram’s last seen field can expose bot traffic

This profile card is the useful part: a hidden mobile number, an ugly-looking account name, and a last seen stamp of 24/08/2026 at 07:48. The surrounding analysis uses that gap to argue for “action without presence” – a pattern that does not fit normal human behaviour.

The practical check is simple: compare new joins, last seen, and your channel’s net growth before trusting the ad platform’s conversion count. If those numbers do not line up, the campaign may be buying bot activity, not real subscribers.

That is the same distortion this Telegram Ads experiment is trying to pin down.
