It has been a problem to maintain and check bitcointalk forum member's posts. Spams and so many posts that are not meaningful can best be seen by bounty manager. Thus it is good in my own analysis to make bounty managers as a merit source.
For what I can see in DmrDmr dashboard for merit, there is a ridiculous ammount of merit being sent / received in the ANN section. I simply do not understand how is this even possible. A campaign and an ANN is simply a commercial thing, I more in favor of not allowing merit in those sections at all. It is just a bunch of people trading and possibly selling it for actions that do not contribute to BC Talk.
I am talking about 12% of the total merit in the forum being exchanged, basically sold, in the Ann section. I do hunt for bounty, so I am probably not the most popular person here in Meta, but I tend to keep my posts on topic and do a honest work for a not very large pay. As far as preventing farming, I am on the same boat as the Admins and Legendaries.
