You are just not the target audience. Meta is a trillion dollar company and their algos are extremely optimized.
It probably detected your gender (male), age, location, social graph, as a combination of all these that you would be interested in AI-generated softcore pornography. And for the average user with your stats, they absolutely are.
Of course, nobody at Meta hardcoded their algorithm to do this: it’s just naturally found out the kind of content a person with your specs loves. Sorry, OP
