I looked at the posts in the OP and I noticed two things:
1 - You cited many posts from Review Master. If you do become a merit source, I would encourage you to spend your merit to a diverse group of people, while still spending near your maximum amount of merit.
2 - Many of those who you cited seem to make fairly good posts, but they all seem to have fairly low amounts of merit. This could be an indication that some of the local threads that are not large enough for detected subs are lacking source merit.
