In addition, there is already a
thread in the Meta where DdmrDdmr regularly reports on all participants who are close to increasing their rank. All participants publishing here their statements about insufficient merits really look like beggars because the forum has long known everyone who may really need a few merits to increase in rank as soon as possible.
Modesty in this thread is not the predominant quality of the nominees.

In short this thread got out of hand after some users actually managed to get enough merit and rank up. The OP's idea may be good, but it's hard to prevent some things from being great once people's interest increases.
I think now the OP needs to add a bit of custom rules to the thread so that the actual countdown post that is far from being ranked isn't done by some users anymore. Less than 10% - 15% to the next rating I think is good and would probably be great to consider. But I'm sure, some user are starting to notice it and I think the interest is going to drop a bit now.
