That feels like you're asking about a different system, based on centralized authorities like HN or Reddit. Matrix is decentralized by design, similar to IRC, so you'd have to pay off a _lot_ of people to buy your way into every server's good side. Because no sane server is going to accept the trust list of any other server it interfaces with just because it happens to also be a Matrix instance.
