Many ideas have been discussed here about adding 2FA as a next level security for accounts to verify they're legit and not just a spam bot account and chat. (See: https://twitch.uservoice.com/forums/933812-safety/suggestions/41306257-adding-2fa-to-chat-as-optional-filter)

What I propose here that is different those ideas is adding a CAPTCHA solver puzzle for people who want to follow a channel. And I'm not talking about those silly Text Based CAPTCHA solver puzzles that are distorted with upper and lower case characters and other things, but an image based CAPTCHA solver puzzle.

1. New followers will have to solve a CAPTCHA, a One-time Only process before the follow goes through.

2. Non-Followers sending chat messages to channels will have to solve a CAPTCHA in order to post messages in chat, and is NOT One-time Only, and will have to redo a CAPTCHA every 45 Minutes.

3. Regulars, VIPs, and Subscribers are immune to needing to solve a CAPTCHA portal to post messages in chat, providing they have verified their email and phone number on their account, and that their accounts are older than 90 days, and already completed a One-time Only CAPTCHA portal.

With these 3 things, this will mitigate the most common types of abuse, bot spams, bot follows, hate raids, etc... Requiring the user to solve a CAPTCHA portal would need to be an essential feature globally enforced to prevents these things happening on the platform in light with what's going on with all the hate raids that are going on, it would also enhance safety of its users on the platform from abuse, harassment, etc...
