fraudster

This is something that I don't know how to add in the Telegram group. In the past, when I was studying, people would get airdrops, and suddenly a large number came in, which I couldn't delete, and I couldn't withdraw either. Last time I said their contract address was incorrect, and they immediately kicked me out. Seconds later, a large number of people were added back in, as if they were harvesting vegetables in bulk. It looked fake; is it a scam? Does Binance have such official projects? Can it double in a month, 100% guaranteed, and increase several times in a month.
