Facebook is scam.
Why I say this?
Not only fake tradingview advertisement but there are fake advertisements with brands like Binance, OKX, Remitano, Kucoin and many others. They are too raw scams as their links can be easily seen and known that it none of those links are from those brand official websites.
What did I do?
I reported those scam advertisements to Facebook and it took them one or two weeks before they responded to my reports. Their replies are they disagree with all my reports and won't delete or ban those advertisements on Facebook.
Those advertisements are scam but how Facebook handle reports against scams is even more scam. You can try to do report and verify what I said.
If they are responsible, they must verify those domain links before approving them on those websites. They are irresponsible initially and when handling my reports. Double irresponsibility and scam, it is Facebook.
Facebook is not safe place for newbies or vulnerable people since they didn't regulate well their platform. They let those fake sites spreading around and what's worse is they spread fast thru advertising their scam in that platform.
I've seen so many times those fake Binance,OKX and other platforms promotions you have said, then click report of all those ads I see hoping they take action on those reports.
We should be more responsible to verify since not everything we saw online is real. Also it will be good if we warn our friends about those scams so that they won't fall from scams.
