Spam bots and Trolls in chat constantly harass streamers with new accounts and get around the bans using VPNs or other tools, Follower only and Sub only modes can discourage new viewers from participating in the chat and can Stunt channel growth. Please allow a new feature which prevents brand new accounts from talking in chat, or more precisely, a feature which requires the account to be x days old before they are allowed to talk in the chat. That way new viewers who have been on Twitch for a while can discover new channels and participate in the chat while trolls who specifically target streamers have to wait days, weeks or months before they can do anything in the chat.
