Right, no, it’s not specifically listening for PRIVMSG–it’s trying to receive any data, the same way it receives PRIVMSG, PING, etc. (and it does receive PINGs from the server). But no WHISPER tagged data comes through when I try to whisper to it.
Edit: Think I realized what my issue is:
:tmi.twitch.tv CAP * NAK ::twitch.tv/commands
My capability requests are getting denied. If anyone has tips on how to resolve this it would be greatly appreciated.
