One filter that has worked for me last 5+ years is duality check. Seeing what people tell you in one on one, what they do in real life and how they project on social media.
We are all craving for importance and, social media is a melting pot for the same. It is also a place to distinguish between Zebra and Donkey.
In the end, our life is short, and we need to be with people who believe in us and are virtuous enough.
