Detecting lurkers up to no good in Twitch is tricky… “Lurkers” are defined as viewers that don’t chat or actively engage. They’ll mute the stream or could be watching different streams at the same time. Since some viewers tune in to enjoy the streamer's gameplay only and may not want to join in the chat, this type of lurking is acceptable on Twitch. The “Viewer Count” shows the number of people just watching, those with and without accounts. The “Viewer List” includes those connected to the chat even if they’re not actively contributing. It’s probably safe to assume that viewers who genuinely want to watch, with no intention of speaking or negative lurking intent, will not connect to the chat.
