There are a variety of reasons why content is not appearing.
The content may require moderation, which might require review by a human (we are aiming to have this take less than a day). It is also possible that through human or automatic moderation, it has been tagged as content that should not be shown (e.g. in search).
Temporarily, unrelated to moderation, there are some searches that are limited to increase performance.
If it has been more than a day and you feel some content has been mistakenly moderated, please email appeals@character.ai with a reference to the content and we will review.
