This is my first time seeing that link. Has Telegram made an announcement about that? Since when it's available?
It's in telegram's FAQ
Q: There's illegal content on Telegram. How do I take it down?
All Telegram chats and group chats are private amongst their participants. We do not process any requests related to them.
But sticker sets, channels, and bots on Telegram are publicly available. If you find sticker sets or bots on Telegram that you think are illegal, please ping us at
abuse@telegram.org.
You can also use the ‘report’ buttons right inside our apps, see this post on our official @ISISwatch channel for details.
Note: If a scammer is pretending to be you, contact @NoToScamQ: What do I do if my username is taken?
Telegram usernames are distributed on a first come — first serve basis.
We understand that certain usernames are part of an online identity for some of us. If your desired username is already taken, we will be happy to help you acquire it for your account or channel, provided that you have that same username on at least two of these services: Facebook, Twitter, Instagram.
Due to the fact that one account can register multiple bot and channel usernames, we reserve the right to recall usernames assigned to unused bots and channels, as well as openly squatted usernames.
To request a username, contact @Username_bot.
