I think I remember this quite well and one of the main reasons being that who knows what that post at the time got you, even though it wasn't rewards.
It's the same like content creators starting out on youtube or elsewhere, none make anything early on but without the early content they won't get followers/subscribers/etc to get views on the next post/comment or to have convinced curators that this author has been trying and deserves rewards on the next post, etc.
The general consensus is to just not repost, if you had made some slight updates to it then I hope you weren't zero'd (can't recall that fact), but the 7 day window is a fact of the blockchain and people who repost may often get the same voters which goes against stake distribution.
It's not something that happens often, often it may even go unnoticed. I hope that interaction wasn't a reason to keep you from posting more or being active.
