True, reputation has always existed. But after a certain scale, quantity becomes a quality of its own. There’s a big difference between word-of-mouth at a single bar and a centralized, algorithmic reputation score that can follow you across dozens of services. If one bartender thinks you’re rude, you can go to another bar. If one nonprofit doesn’t like you, you can still volunteer elsewhere. But when a social media company or platform blacklists you, it can ripple through your professional, social, and even financial life, because their influence extends far beyond one community. That’s the leap from local memory to systemic gatekeeping.
