just letting you know, there is someone trying to scam with a fake moonbux' thread. Be careful
You should do either of the following (or all of it):
(1) Post a thread in Meta about the user/PM you received.
(2) Report the PM to a global moderator/admin (Cyrus for example).
(3) Leave negative feedback to the user that tried to scam you.
(4) Block all future PMs from that person.
[(1)&(2) being the important ones, (3)&(4) being optional/additional]
