This kind of scam is already outdated and you could easily identified it, the best option here is once someone message you, which is not typically normal , its a scam because no one message you out of nowhere especially if you don't know the person asking for money, this scam, like email and also in viber, or any other platform of messaging is normal this days you just have to block them automatically because if you try to interact you might also click a link accidentally and you don't want that.
