Identification of Telegram users through authorization on external statistics portals

I am sharing a new way to identify the profiles of administrators of anonymous Telegram channels.

1️⃣ Go to https://tgstat.com or https://telemetr.me... Or create your own bot that requires user authorization (for example, using https://t.me/FleepBot)
2️⃣ Click [Login to the site]

3️⃣ Copy the link address from the [Login via Telegram] button with your personal authorization key. For telemetr.me, after clicking the [Login via TG] button, the authorization bot page will open in the browser. It is from there that you need to copy the link address next to the [SEND MESSAGE] button with your personal authorization key.
4️⃣ Mask this hyperlink. For example, under the sentence “register and take advantage of all the benefits of the Telegram statistics service.”
5️⃣ The user is authorized. You see information about his Telegram account in the TGstat or Telemetr account, and also access the portal from his profile.

If you transfer a user to your bot (for example, designed to punch data), then the results of its work may include the complete open data of Telegram users, an authorized phone number and a list of requests.
