Earlier quoted context omitted.
I'm not the same person, and the question still applies. If you're so pedantic, then, > Since when is a social media account required to leave reviews? It's just as absurd when written this way. But, please, show me the exact place where Airbnb (or any other big company) says that a social media presence is required to leave a review. I'm waiting.

Nobody writes their spam detection algorithm as policy, but there is also no evidence whatsoever that social media presence was in any way shape or form used to make the decision here.
