Side-comment: is there a type of shadowban with HN where my posts do not make it into the frontpage, even 2 or 3 or more pages deep?

I've seen this with a few of my posts recently where they appear in the 'new' and 'show' or 'ask' tabs, but not the frontpage.. even 300 posts deep while similarly aged and upvoted posts are on second page.

edit: now it's on the frontpage! Guess it just had to hit a vote threshold.
