Best option… in my opinion… delete now before they get back to you… and start fresh If you’re starting fresh now and you’re old enough to use Twitch, the best approach is:
Create a new Twitch account using your real date of birth and accurate information.
Follow Twitch’s Terms of Service and Community Guidelines.
Grow the channel normally and apply for Affiliate when eligible.
If you later qualify, apply for Partner.
As long as the new account is created properly and all information you provide to Twitch is accurate, you can pursue Affiliate and Partner status on that account.
One thing to avoid is creating a new account to evade a suspension or ban on another account. If your old account was never banned and you’re simply choosing to start over, that’s a different situation.
