Luckily I'm not a DT member, so that damn user didn't target me for that weird PM. 
I have not received the PM yet which means I am not in DT too 😉? My bet, the user is targeting people with some other criteria not just a DT.He may start with DT members, then he will target random members.
In my opinion, that account only tried to make chaos since he won't succeed if he targeted DT members. DT members won't be easily trapped by that weird PM, only careless members can be the victims.
By the way, it is a bit strange why he did this. He must know if he won't have a chance to succeed, but he did it. If he really wants to make chaos or suspicion among the members, what his goals exactly?
I also got that weird PM.
