Personally, I wouldn't mind if someone took 1000 merits from me, I didn't ask for them or invent the merit system, and I had already reached Legendary rank before the system came to life. However, I do not think that we should go to such drastic measures to punish some individual cases that behave like leeches on the forum, but that airdropped merits could be taken away from those who really proved to be members who have no contribution to the forum.
I am against this proposal of removing airdropped merits. It doesn't affect me personally, just as it doesn't affect you, but that's not the point. If a decision was made to introduce this system, which also entails airdropped merits, it seems a bit unserious to make changes to it now. The system works, it is not perfect because perfect doesn't exist.
Yet if you consider that the issue of removing airdropped merits has been the subject of debate many times, and that there has been no concrete response from the admin (as far as I personally remember) - I think such a move is very unlikely.
And hopefully it stays that way. I would rather have more people come to the forum, than finding ways to drive those who are here away. If they break rules, use the ban hammer.
