I just came across a wave of reposts about +42777 on Telegram. It turns out this is a real issue, not just a meme. People are joking that if you add this number to your profile, you supposedly get premium, and many have actually tried. The result — banned accounts. Telegram's logic is simple: +42777 is reserved for the official account, and if you specify it, the system thinks you're impersonating Telegram and blocks you. It's strange that such a trap works, but the fact remains. I saw screenshots of people who lost access to their accounts. If you have +42777 in your profile — delete it immediately. Don't risk it for a joke, it's not worth it.
