Twitch's official response: https://x.com/TwitchSupport/status/1848191418377830708

We wanted to address concerns we’ve seen about whether we’re preventing Twitch account sign ups in some regions.

When signing up for a Twitch account, you can select an account verification method – email or phone – for added protection. Following the October 7, 2023 attacks, we temporarily disabled sign ups with email verification in Israel and Palestine. We did this to prevent uploads of graphic material related to the attack and to protect the safety of users.

Signups were not disabled, and we continued to see sign ups from both regions. Users could choose to sign up with phone verification. We’ve learned that, inadvertently, we did not re-enable email verification sign ups for either region.

We deeply regret this unacceptable miss, and the confusion it has caused. We’ve fixed the issue, meaning all affected users can sign up with email verification.

We’ve also heard concerns about whether our Community Guidelines apply to all content on our service. We continue to enforce our rules as consistently as possible, and are actively reviewing content and taking enforcement action where needed.

Any feedback regarding the accidental region locking will be directed to this megathread. Please keep your comments civil, thank you.
