Feel free to add a technique you were able to discover and let everyone aware to avoid being scammed. When you add yours, I encourage to share a little bit of the background of how you discovered it.
My whole campaign management business runs in Telegram and Bitcointalk PM and it's very easy for me to get trapped by the scammers. It requires me to stay alert always. But scammers try their everything to take their unethical share. They don't just try to fool me but they try to fool my clients too.
Other day Sinbad Management was telling me:
I think someone is trying to scam me with supposedly your account
My response was as usual, that's not me. Sinbad management is smart enough to understand the environment too. We both were aware so no harm happened but if one of us was not good enough to realize the attempt then there could be some financial loss.
Later the same guys (I don't think it could be anyone else, because both happened in the same day in a difference of few hours) PMed me pretending he is Sinbad. He failed though however it took me half an hour to understand the trick.
Let me share two screenshots (real username removed and conversation with real Sinbad also removed).
1. Original Sinbad
2. Fake Sinbad
The thing that struggled me to find both username were the same. I checked letter by letter, both same. Nothing was there to differentiate the two accounts by username. But I knew there were something that I was missing and I did not give up until I found it.
When I was clicking on the original Sinbad username it was copying in the clipboard but when I was clicking on the fake Sinbad username it was showing the Sinbad profile and SEND MESSAGE link was taking me to original Sinbad chat (I was lost there and started to think Telegram have this error and the fake one is the real guy).
What the scammer did is:
Check image 1 and 2.
The scammer updated his bio with the same exact letters and symbol that Sinbad username has in Telegram. By default Telegram set your bio information in the same place where they display your username if you do not set up a username. The scammer discovered this little trick and utilized it with hope to scam either me or the Sinbad management.
Next time when you are receiving message then check twice. Under the username what does it say: Username or Bio?
