What are you supposed to do when you get a message from someone on YouTube that says they want you to send them a Telegram?

There's a number of people whose videos I watch a lot and sometimes post a comment on and, every so often, one of them will respond that they like what I said and want me to Telegram them. They give me some kind of number, I guess it's like a phone number, but I have no clue what they mean by Telegram or what the number is for or even what Telegram is (other than something like, Western Union)! I write them back via the same video to ask them what I'm supposed to do and I never hear back from them! People like, J P Sears, Paul Joseph Watson, Bill Bruford, Robert Fripp, Liberal Hivemind, Parlogram Auctions, etc.. It looks to me like I'm getting these from the actual video makers but, I recently discovered that the one from Bill Bruford 2 weeks ago was bogus!
