3 weeks are at the end of the bell curve
This I understand as that someone posts every hour a reply to get attention but my replies every 5 days are approved always. Approvals are by mods iirc.
Then there must be an info that I received but there was no info. No reason was given.
I did that 10 times but Tejdxa warned me only, after that I had 6 or 7 close calls of me almost pressing the reply button but closing the tab.
