100 sMerit/Month is not unlimited; it is 100 sMerit per month. Merit sources are the only way for there to be an increasing amount of merit distrusted around the forum, in order to compensate for the necessary merit needed to rank up new accounts at a reasonable pace. Without a Merit source we would just be trading around merit until sMerit has depleted.
I am interested in the "It is not allowed for merit sources to sell their merit", as this implies it is "allowed" for other users to sell their merit.
I thought of unlimited as a source that will go on producing sMerit.
Yes, it is limited to 100 per month, 1200 per year , 120k a century but it will never dry out.
Ranks now matter more than they have recently, I don't understand why you hope that be to a mistake. Do you believe there are more than 14 members each month that are deserving of ranking themselves up to hero, based on the merit of their contributions?
The 14 hero members was the maximum with points concentrated. (Yeah I havent' taken into account the 1750 sMerit and the next 875 that gets created ...so on.... basically x2)
Now, most of the merit point will go of course to the oldest and wisest members on the forum (as it is normal) , so how much of it could go to new accounts? Probably 1-5%.
Those points might get too valuable, just as accounts did as you need 10 to be able to "work bitcointolk" or "do bytkoin". Leading to circles trading them.
But already Lutpin addressed the issue:
I think the amount of merit sources is supposed to increase over time.
