If you notice your chat messages show up in the chat feed but don’t appear on the streamers in-screen chat, you have been shadowbanned.
Twitch will still take your money for donations, subs, etc, but your feedback won’t be seen by anybody but you. This shadowban does not appear in the appeals page and can be applied randomly and intermittently. You are never informed about this by the way. You’ll likely be talking in a chat and assuming you’re being ignored. Hop into a private tab and load up the stream where you’ll be able to notice if your messages are missing in chat.
From my observations, there seems to be some type of algorithm/system that determines who to shadowban. I’m assuming it assigns extra points for factors like VPN usage, Linux, and adblockers. Once you’ve been shadowbanned, switching one of those three will not work to unban you until some arbitrary timer expires.
I’m posting this in case anybody else has experienced this and felt frustrated and isolated. You’re not being ignored (unless you’re a twat and are being ignored). You’re just being punished by Twitch for being privacy conscious.
You can just make a new account and blam you’re free from the ban on your account. That’s why IP bans exist.
VPNs exist and then boom IP bans no longer matter. Hell, some ISPs give you a new IP if you just restart your modem. IP bans sweep up clusters of users behind large gateways like college dorms or carrier-grade NAT.
IP bans do not work and I’m sure twitch seldom uses them, the exceptions being VPNs and cheap/free VPS services.
Think of it from the reverse direction. If you have a twitch account in good standing that’s verified with a valid email and has no violations, why all of the sudden would it make sense to apply a ban to this account? Perhaps preventing new accounts from being created on a sketchy IP could be a sensible solution, but shadowbanning an existing account makes no sense and is a lazy approach to security. In addition, fingerprinting makes it so a service can easily differentiate between users using the same IP.
What if the account is compromised? Now the spammer is able to do their spams freely on the IP address.
It’s just a hell of a lot easier to black list the entire IP than to try to manually let in small percentage of people who use a VPN AND want to comment or whatever.
