So, the problem is that when a streamer is hosting someone else on twitch, the plugin tends to record the hosted user. I think that this should have an option, such as --no-host to prevent this from happening.
Operating system and version: Ubuntu 16.0.4
Streamlink and Python version: Newest Versions
See the --twitch-disable-hosting parameter:

Closing this since it's solved.
