Meta sued “to prevent them from advertising CrushAI apps on Meta platforms”

Dude, it’s your platform, Meta. You decide who uses it. If someone is abusing your platform, that’s a you problem. Vette your customers like Apple if need be.

… the exact same image containing nudity was removed as a normal post on Facebook but allowed when it was part of a paid ad.

There’s your solution. Reassign a couple content moderators since they’re on the ball. Much easier to review/ban a commercial account than individual posts anyway.
