Few days ago YFMoonshot bounty telegram group deleted. Their bounty finished date is 19 September and they locked the thread today which is before the deadline. I asked their telegram that why thread is locked but they kicked me out from the group and banned me. Their behaviour looks like suspicious. I think they can scam bounty hunters.
You don't need any other proof to tell you this is definitely a scam project and most probably hunters will not get their reward for the hardwork they put in to promote the project, most of this Defi project are bad news hunters should do well to stay away.
