What is the reasoning behind the not rusty warning?

I dont think redundant questions are the problem. But people’s historically short responses on reddit definitely were. Responses like “have you tried googling it” or “the question has already been answered, try searching before you post” do nothing but ostracize the person asking and make communities unwelcoming. I would like to see Lemmy more understanding, as to encourage and attract novice individuals in communities they are interested in
