Good to see this one on the top of showhn. I see that you shared the same 2 days ago and the one before 8 days ago https://news.ycombinator.com/item?id=23849221 what has changed since then?
My understanding is that this is acceptable practice. There's a lot of luck to a post reaching critical mass on HN, so if you happen to get lost in the noise, you can try again. Trying three times does not feel at all egregious to me. As long as you don't delete old submissions to hide what you're doing, I think that's in line with HN's rules.
One notable difference is that today is a weekend, which means there's less traffic on HN but also less competition to reach the front page.
By looks of it you seem to have misinterpreted my question. I never suggested it to be a bad practice but rather was curious if there’s was something changed to post it again, I certainly would.
