Why Does Reddit Mark My Post as Removed When Moderators Can Still See It?

I posted in a subreddit and can still see the post while signed in, but friends say it does not appear in the community feed. A moderator also told me it is visible to them. Is Reddit quietly filtering it, or could this be a setting or review state I’m misunderstanding?

I’m trying to figure out whether this points to Reddit spam filters, a community rule, or a difference between what the author and other users can see. If you’ve run into this, what did the post look like from a logged-out account?
