Ask HN: Why there is asterisk(*) attached to my post and it got shadowbanned?

I have created a personal project of chrome extension and wanted to share it with community (with Show HN tag). It seemed to be submitted correctly, yet my post is blurred (turned to grey) with an asterisk(*) and cannot be seen for anybody except me.

I'm still kinda new in this community and not sure what went wrong and why.

Thanks
