Anime profile pics are warning signs
Anyone using an anime profile pic is not doing so because of appreciation. They’re sending a message, intentional or not. That message is “I am hiding my appearance. My appearance is a deal-breaker, and I am well-aware of it. Rather than put forth any effort to improve myself, I choose to represent myself instead with animated characters indistinguishable from each other, and renowned for being associated with fans with unpleasant, awkward, and antisocial behavior.”
