I was surprised to learn that the thread was started in 2018 and has only had 12 successful participants to date, and that compared to the other merits to Newbies/Jr.members threads, yours has the least amount of activity. I believe your rules killed the thread; why would any Newbies/Jr.members go through such rules for only 1 merit/post & 3 posts max. When they could create encryption and sign a message in the Ognasty thread in fewer than 24 hours, they would receive a total of 6 merits. Either the rules are not friendly enough, or the offer is too poor.
Here is a link and proof that the thread did happen
https://bitcointalk.org/index.php?topic=5085605.0It was meant to be only for Newbies and Jr. Members. I expected much more activity in it, but it died out after a while. If you go through the applications, you will notice how many times I had to reject certain members because they aren't capable of reading and understanding what is requested of them.
