Firstly is that actually true? I feel like I've seen any number of interesting posts from brand new accounts.
Secondly, if you have "spent weeks building" something it will not kill you to wait for five days to tell us about it.

Nothing springs to mind that is that important that:
• It can't wait a week or two
• Would be of no interest to conventional news organisations
What specifically did you have in mind?
Because at the end of the day, without clarification, this sounds a lot like "Spammer would like to know how avoid the spam filtering please."
I created a new account, posted legit content, and none of the content appeared until ~5 days later.
> it will not kill you
How do you know it will not kill me?
What if I don't have to pay this month's rent and launching the site today instead of five days later amounts to $500? Both of these are true for me right now. The creators of HN can't possibly know the cost to a user to post something.
How did you estimate that "it will not kill me" also means it will not kill my spirits to not try again? How do you measure this cost?
> Nothing springs to mind that is that important that:
Merely because nothing springs to mind isn't proof that no such thing exists.
> What specifically did you have in mind?
I have different things in mind for different sites.
But, if you don't like it, then it is relatively easy to start your own community site. Something like Lemmy or kbin might be suitable for you. Let us know how it goes - and whether you solve the spam problem.
I did and I did.
