Didn't know this existed, thanks for sharing this.

I knew there were people who get new merit every month and by the data on this link, this is what it comes to be:
- 109 merit sources with a total merit generation of up to 33940 sMerit per 30 days

So there are 100+ people who get almost 33,000+ Merit every month which is almost 311 sMerit per person.
That assures that merit will never be exhausted on this forum unless these 109 people stop accessing the forum and the sMerit(s) for others get's exhausted.
