I thought that Facebook would b all crypto-related ads regardless of whether they were real or spam?
Overall, the Facebook team is active to remove such scams and I also believe that people will easily find out that it is a scam, although I think SHIB coin itself is a scam on a larger scale.
Ah shit! I forget to add the link facebook post in op. And now I can not find it. Provably it was removed by reports.
They have become very strict so it will be faster to report to delete content than to create a topic here.
