New posts by 1-postcount and 2-postcount forum members always go into a Moderator Queue. You have to wait for an Approve before a post becomes visible again.
Spammers are using artificial intelligence and/or results from Google (a copy of another website's forum post) to post legitimate posts, and then later editing them to spam.
These kinds of things often bypass the spam filters so we've had to institute a Manual Post Approval Queue for 1-post and 2-post newbies.
Right now, you're at approximately the post threshold which means you've now transitioned to the automatic spam filter, so you should be able to post/edit with zero delay.
Later this year, we'll update the system to be more clear to alert new posters that their posts have been put into a moderator queue.
