Using the CAP REQ twitch.tv/commands option in IRC, I am receiving CLEARCHAT messages–at a rate of about one every 3 to 5 minutes–for users who do not appear to be in chat and have not sent any chat messages. Furthermore, I have verbal confirmation that these CLEARCHAT message do not correspond to any moderator actions.
For context, this is occurring when the channel is live and has generally anywhere between 700 and 3000 viewers.
I guess that’s technically possible. The channel does use Nightbot, but as far as I am aware that is not an advertised feature of any of the main bots?
