Facebook Ads Phishing

You are just new to Facebook. They don't actually mind being complicit to crimes such as phishing, scamming, fraud, etc because time and time has shown that laws don't actually apply to these companies, so they adapted accordingly. Spoiler alert: flagging these will often not do anything either because according to my experience obviously illegal content doesn't actually violate their community guidelines.

Install a good ad-blocker (uBlock Origin on Firefox, AdGuard on Safari, etc) and consider anything that has any kind of connection with Facebook to be malicious by default.
