This was an example, once a week, such accounts change hands. You say merit system prevents changing hands but merites turned into a form of bargaining.
Is there a DT member who speaks your local language? These things need to controlled radically by the joint decisions of any local DT member, Merit source and maybe the local moderators.
my suggestion is very simple !! Remove unused smerites after 1 month.
my suggestion is to use a fair forum and rank distribution
Dont want to sound harsh but community suggestions are rarely taken up to administration. But it is always appreciated, even when we cannot do anything about it but live with it.
