I feel like everyone here is misinterpreting what the author meant. The site doesn't publish your messages without consent. In fact, from their FAQ:

> When uploading a thread as an individual, we email a permission request to each non-anonymized person who contributed at least one message to conversation. A thread will only go live if there is unanimous consent. This means that if even one person hits 'Decline' or doesn't respond to the permission request, the thread will remain private.
