WordPress Origin Story

I started using WordPress over a decade ago as part of my web marketing work for small businesses in Osaka. What began as a tool for building client websites became central to everything I do — from site optimization to plugin development. Building MUTE Spam Blocker was a natural next step: I wanted to solve a real problem that my clients faced every day.
