do we know how to apply/edits these filters as a creator? one of my posts is being marked as sexually explicit because it's a shirtless (male) mermaid :)
You can't. The algorithm has to do that.
It's also why even with mature content turned off, a bunch still gets through. Bsky doesn't want us to moderate our own content, they have to do it for us.
Well, you can set an “adult content” mark on your post as long as it has media in it. Just tab the symbol I circled in here while you’re creating your post.
