As far as I know, there was a similar story here on this forum in the past. Someone posted an address and promised to choose someone (randomly) among those who sent him btc and give a prize to that person, but he never did! Also, these kind of activities were forbidden after that. I feel like you guys are going to move the project out of this forum and hide behind a coin.
To be honest everyone who sent money to such an address fully deserves to be scammed. How stupid must someone be to send money to an unknown address with the hope to be returned even more money?
