You didn't make many posts during 2018 to 2020, 70 posts in more than two years are very few.
It is good to have about 17 Merit with 70 posts. This indicates that you are doing a good job. I wish you more success.
It is too early to celebrate It is still a long way to reach Full member.
I like you, I am back again and will soon have 17 Merit like you
