I had tonnes of similar entries in my campaign, you can say this is normal behaviors of bounty hunters these days, only a good real BM can detect them really fast and give them Zero stakes/ tokens. Just give them negative feedback and go ahead, man.
In my last campaign, I got more than 8k entries and half of them tried posting someone else's work.
Yes brother you are right. I also worked in your previous bounty "Psyche" and I saw so many scammers. By the way i'm not a DT member. So kindly give him a NT so that it will better lesson for him.
