I think what further drives this feeling of disgust is because the community is so popular for the kindness and generosity it has. Seeing some of my friends that are new to the franchise and treating it like a business rubs me in such a bad way, but I don't really feel comfortable saying anything other than "haha nice" whenever they message me talking about how they managed to get X villager for 10 NMT and are about to flip them.Yup this is the unfortunate consequence of being generous, some people will take anything they can get, even if it means taking it away from someone who actually wants it.
Not to say I have a problem with people making profits on games in general and I'm well aware this happens for literally anything with a market. It just feels incredibly out of place for a game like this.
