You might face a ban on Twitch for using a modified client, even if it's technically just a downloadable mod. The platform enforces its own rules beyond the game's policies, and such actions are generally considered violations. It could fall into a gray area, but it's likely to be treated as a rule breach.
Are you sure about the ban question for Twitch? For Minecraft, it's a definite yes.
You can't be removed from Twitch, but if a mod on a Minecraft server tells them to watch your stream and they notice you're cheating, they can easily ban the server.
Twitch won't ban you, though you could face a ban in a Minecraft server. It should be okay... I have a friend who streamed "Greifing" servers on Twitch, and it worked out fine.
It's not ideal if someone discovers your server and another player spots you on Twitch, commenting about the username being suspicious.
