Of course it is. You’re passively benefiting from other people’s hard work and maturity without contributing anything yourself. The people who are on the server to RP are there because they want to see other people RPing and be there character in a fantasy world. If all you do is watch passively, you’re getting without giving and breaking the immersion for the people you’re benefiting from.
Don’t come to an RP realm to mooch off of the community. You are more than welcome to join us, in fact, we encourage it.
