the first one got locked as soon as someone shouted
SCAM ALERT so it's probably okay.
if it's not okay then give it some time and a mod will probably delete it. it was just made yesterday
The first thread was locked by most likely the OP when he realized that he will need a self moderated thread for his scam and he then created a self moderated thread in order to delete posts advising possible victims of his scam.
There is only one active/unlocked thread so IMO it should be okay. It would also be okay if someone else created an unmoderated thread about that thread. Also, I think it is pretty rare that duplicate threads get moved to the trashcan when there is a number of replies but would rather get locked.
