I really don't see the harm done here.
Merit is supposed to stop shitposters from ranking up. "Airdropping" 30% of Full Member onto spamming Newbies just because they posted at the right moment goes against this:
While we will not be directly moderating this, I encourage people to give merit to posts that are objectively high-quality, not just posts that you agree with.
The 30 Merit on higher ranks makes less of a difference than it does for lower ranks.
