A couple of days ago I joined the Bancor Telegram group. In the same day I was approached by someone having the name "Bancor Technical Support". It was a scammer. Be extra careful.
This kind of thing is happening a lot now a days and not only in Bancor. Everyday I keep getting added to some fake binance telegram groups claiming that they are running some promotional event where we will get 10 ETH if you deposit one lol
