You can't be surprised there are scammers and imposters on Telegram. It's very easy to change your username into something that looks like something else. It's almost as if it's designed to facilitate scamming.
As you know, I am still too young in this business. I never thought I was popular enough to be targeted by the scammers.
Scammers don't target popular people, rather they target the fans and followers of popular people.
You not being old in the business is another reason to target you.
I have been trying to understand the essence of that scam.
Do they just want to have 50 free spins of $1 each for themselves and try their luck or they want to initiate the conversation and create such a code with malware and make you send it to people in the forum?
If I were you, I would have delayed a bit to see where they will land. Seeing this post might not allow them continue their activity and we clueless of their intent.
