People generally aren't overly concerned with determining the accuracy/truthfulness/realness of whatever they are looking at. Social media is completely full of heavily filtered, edited, and photoshopped images. There are a whole lot of faces, asses, waists, and entire bodies out there that look absolutely nothing like the images representing them.

Even the text and just the general presentation of reality is suspect. Looking at someones Facebook or Instagram doesnt show their real life, it shows a highlight reel that is heavily edited.

Deepfakes are a drop in the bucket compared to all this. It's very easy to trick someone that is lied to basically 100% of the time already.
