“In May, we removed a legacy feature called Messages and provided users the ability to download an archive of past messages. Due to a bug in the code that generated the message archive files, which has since been fixed, a small percentage of user messages were included in the wrong archives.” reads the statement from Twitch’s spokesperson.

“The primary use case for Messages was promotion; streamers sending out mass communication to subscribers for example, and the majority of messages that were unintentionally provided to another user fall into that category. We have notified users via email and provided them the affected messages for review. Protecting our users’ privacy is important to us and we have taken actions to ensure this kind of error does not happen in the future.”

According to Twitch, the bug only affected the Messages feature, and there were no private messages sent via the Twitch Whisper systems included in these archives.

Twitch users can discover if their messages were accidentally exposed by visiting the website

Searching on Twitter it is possible to find messages of Twitter users that found messages in their archive belonging to other users.

Anyway, Twitch sent a warning message to all affected users.
