] Telegram is a dangerous chat channel? Isn't Telegram a place that never leaks data?
Maybe you made a mistake, but for me Telegram is the real place where we can talk about confidential information. Besides, it is also a place to connect the community together, where the bots work very effectively. I have never really found a place where there is freedom of speech or information security like Telegram

Once I ran into a situation when someone else used my Telegram account. As it turned out, my phone number got into the database of a resource that provides users with services for receiving SMS to the appropriate number to register on many resources, including telegram. Thus, my Telegram account became available to another person and I could not do anything but delete all information and create another account, prematurely changing the phone number.
