It’s called reciprocity. You are getting something from us without giving anything back. The nature of RP is that even a few people who are walking around the world not participating ruins it for the rest of us. People are putting in tons of effort to make backstories, put on accents, and build flavor into the world. If you want to enjoy that, you need to participate.
RP is not a play or a movie for you to come watch. It’s a recreation of a world that you either decide to join and be a part of, or don’t.
