@xChaos I agree, we should all be aware of AI. But I think I can still tell, when a profile is real. For instance, som people who share their faces also share situational photos of themselves with the same face and being next to other real people in real environments.
The consistency across their posts and photos is also a good indicator. Some AI profiles flunk because of inconsistencies.
Theoretically an elaborate profile could be faked too, but I do not think that is common.
