There are users in higher ranks who don't contribute anything, you are right about that but those are a handful compared with low rank spammers.
If a decision is made to do something regarding the airdropped merits I am sure those from high ranks who have not contributed to the forum ever, meaning both before and after the introduction of the merit system, can be singled out manually and demoted if needed. But doing it to everyone in the same way would be wrong.
Someone mentioned Hal - good example, or Zepher or anyone else... May they rest in Peace!
I agreed with you, Pmalek. Even grandfather high rank users have not contributed anything or contributed limited things for the forum, and luckily hit high ranks before January of 2018; they - at least - have not spammed the forum. At least, they did not spam the forum after January of 2018, because they knew their account values very well, and became more careful with each of their posts. However, non-spam posts don't equal to constructive posts for sure.
Things might become much complex on how to classify grandfather users whom won't be demoted because they deserve such ranks due to their past contributions; and grandfather users whom will be demoted due to their lack of contributions (both in the past and after birthday of merit system in 2018).
Therefore, the best thing to do is don't do anything.
