I read dozens of writer's blogs and Facebook posts, and see one particular complaint repeatedly voiced by successful writers. They often feel harassed by certain people -- whether in a mild form (a request to read something), an annoying form (a request that the writer participate in a project) or in an alarming form (stalking-like communications).
In an ideal world, the writer's public would consist of nothing but polite, sane people. Yet we live in a world with many troubled, needy people. If one chooses to become a public figure, contact with people who want something unreasonable is a sad but unavoidable part of the entire fame package. The writer can change his or her expectations of the world, but complaining won’t have much effect.
