I suspect there's a tendency for anything with a public, fully anonymous (rather than pseudonymous) format to eventually become something some people use for the worst things imaginable. For example, people used to write bomb threats and racial slurs on bathroom stall walls at my middle school. Anonymous imageboards are kind of the global version of a public bathroom stall wall. Sometimes there are funny or uplifting things on it, and sometimes the polar opposite.
