Here’s the thing, and this never bothered me until now. I get devices for review. Okay, I used to get them, review devices are used by my colleagues. But when I do get a device that will be returned, this is what happens. Telegram will associate every device you’ve used with you. So if I use Device X, then give it to my small bro, somehow our Telegram contacts will be synced, in read only mode.
This is how I ended up getting alerts that media celebrities have joined Telegram, because I used one device, then it probably ended up at Capital FM and that’s how I get alerted that Cess Mutungi has joined Telegram, including her username and phone number. Right now I’ve been alerted that Maina Kageni has joined Telegram, and I have his phone number as a result.
I can’t be exactly excited, that’s how random strangers end up having my phone number. So any device that has had your Telegram account ends up staying with your contacts in the Telegram cloud waiting for Telegram to be downloaded and the grapevine continues. By the time the phone is at it’s third reviewer, we are all family.
