I asked two major questions. Only one has been answered and I acknowledged it. Am waiting for the second question to be answered and when it is done I will lock the thread. Thank you.
Oh! I did not see that.
In the second picture, the red marked areas indicate dates with big gap between the 3rd and 4th post in that thread. That is between sirius and PrintCoins posts. They are 1 year and 9 months gap between them. Does anyone also know why? Does it mean no other person posted between them until then or there were posts in between them but they got deleted? Was the forum not that active then?
I check the topic on ninjastic.space to notice if any post was deleted between the two posts you referred to and I saw non. You can check it yourself using the link below
https://ninjastic.space/topic/5If you check
Satoshi's topic history, you will knkw that there are other threads created and some people are also creating their own threads too. It can happens this time too that a thread can be created, people will post there and left for like or more a year before they will people will continue to list on the thread again.
But bitcoin forum at that time can not be as active as this time.
