No special reason. I lurk in a "few" channels but I don't write anything. I also don't watch the stream.
It's easy. Just type this into your chat "I know just being in chat doesn't count as a view or viewer. I also know that someone can be in chat without being logged in. That being said, I however still would like to ask you, CommanderRoot, to leave. Thank you!". If I see this I will leave and won't come back to your channel.
