DT has nothing to do with all this. All that is required is that you earn 1 merit to rank-up back to Jr. Member, although that you’ll be a poor goal to be satisfied with. So far, 23.670 forum members have received at least 1 sMerit, so there are that many examples of people around who have done so with a wide variety of styles and content.

Exceptionally, some forum members have created some threads in which they award merit for specific requirements at their discretion, normally for having a near to decent posting history, not really tasks as you place it.
You
Regardless, the key idea is to create content through your posts that could be awarded merit due to multiple criteria. Reporting social in nearly all your posts is going to go against merit always, so you will need to change your focus or stay meritless on this forum.
