Merit-tittled topics are abundant in Meta board because it is really hot. It's also due to the fact that lots of users affected by merit system. That is a good signal about potential successfulness of the system. Many users in the forum have to change to adapt to new system, hence they will be better members as main purpose of merit system launched by admin.
On the other hand, this is also an endemic in Meta board. Lots of newcomers or low-ranked users tried creating spamming topics related to merit issues in order to catch attention and hope to earn merits. Unfortunately, they failed because no one send their rare sMerits to spam, non-sense, repeated topics.
Another explanation for the phenomenon is this one is a new tactic/ strategy from account farmers to adapt to merit system. They use new-account to create a merit-related topic timewise questions, then main account joins and ask for more clarifications. Next step, alt-accounts join and give interesting ideas. Over threads, they give merits to each other. It is likely a perfect strategy for account/ merit farmers to avoid radars in the forum. Those guys use my suggested strategy are so smart, adaptable
Newcomers should use search function of the forum, and Google to find answers for their question before creating new topics.
