I see that there are different threads in the section of people who have been appointed merit source and I want to take this comment to congratulate them.
As for the topic of the thread I don't think changes are needed in the system. Especially if we are talking about big changes. The system allowed me and many others, without being part of a local forum, or knowing anyone on the forum, to be able to reach the highest rank. Also, in my case, holding controversial opinions and having heated discussions. Sure it is not 100% decentralized but such a system is impossible in terms of merit because of the problems that have been exposed. It supposes a kind of oligarchy, because theymos appoints the merit sources and then they have more capacity to distribute merits. But it is an oligarchy that works.
Shout out to @Hhampuz, Your Rollbit campaign is the popular destination of merit farmer. Try to check most of your campaign member post history and the way they get merit.

Shout out to you, Xiestar. Try to become a campaign manager and you can run your campaigns in whatever way you want

Of course, it couldn't be missing in the thread the enlightened person who is giving lessons to the active manager who has successfully managed the most campaigns, lol.
