I was surprised when I saw even this scam site open on Facebook. It's not about ads only, I don't know how that is possible to manage but their site opens on Facebook inside and looks like the real site. This would definitely mislead newbie investors who aren't well aware of the crypto scam. However, creating awareness would help at least forum newbies.
These scammers have done it on Libra they will also do it in Metaverse, people are aware that Facebook has an intention to create its own coin and many people are waiting for that to happen but scammers are quick to sell this to people, and they are utilizing Facebook ads to scam people
if we stumble this on Facebook and we know that this is a bogus project be sure to report it, like Google they are not going to take action unless reported, it's unfortunate that Facebook prioritizes profit over the financial safety of their users by checking all the ads that they are showing to users.
