I completely get what you're saying, but you're probably underestimating how many ads are being submitted on Facebook's ad platform. That also includes test ads that needs to be manually checked if they'd go the manual route. While I definitely cant give you a number, trust me that the ads that are being submitted are A LOT. I'm saying this as someone who is active in the internet marketing niche.
Yes, most likely I'm underestimating the number of ads in my calculation and it's far more than 6,000 ads per months, I don't have any numbers too. But even if the numbers are bigger it shouldn't be a problem for them to check which ads are legit. According to
Statista, Facebook has 35,000 employees and that's not much for a company of that size. They are saving costs wherever it's possible so in reality it should be far bigger already. While ads are generating their main revenue it's inevitable to hire a few hundred more and set them aside for checking ads until they can ensure to weed out scams.
We all know that a part of Facebook users aren't the most intelligent ones understanding how some things work (especially in crypto) and scammers will take advantage from it.
And if Facebook isn't capable of selecting ads they aren't capable of running a global currency safely.
I get you that it'll cost Facebook a little bit of their earnings but my main point is that they have to ensure to review them because it's their main revenue source. They are just out for the profits and the users are their useful idiots.
LOL
Dont ever trust facebook when its come to money. Zuckerburg always think about its interest first. all they want is money that's why they allowed such post to be sponsored. look Facebook always automatically updated it belong apps without your permission. Video post is always reviewed manually before it get posted i think they can do the same when its comes to advertisement but they don't do that because they want their money. Facebook is not trust worthy to be trusted with our money that why i don't like Libra Project.
I don't like it too, Facebook has lost any credibility very long ago. Profits first, users last.
