All the newbies just ignore unsolicited PMs to you and even to the oldies; these scammers will choose the newbies first because they're not aware of how they can be scammed. Especially if it involves making some money and they want you to go to another website or messaging app because they can get away from you easily if you've been brought to there. And do not be greedy because that's where it is gonna start for someone to entertain these messages. If you are not greedy then you're not going to entertain them.
It is true and not only for newbies. Any PM from anyone who is either a newbie or a legendary account, but if comes with a very good offer - such "too good too be true" offer - must be considered very carefully and cautiously. It's because such offers are unrealistic and almost likely 100% scam offers.
It isn't right to assume PMs from legendary accounts are not scam offers but in general scammers try to send PMs including offers that can catch attention of receivers. Receivers who are careful, not neccessarily to be experienced, can see it is a scam offer and ignore it. Receivers, oppositely, who are careless but greedy enough, will believe in that offer and get scammed.
