I agree with you with the end of the account farming.
But for your earlier statement, I guess theymos gave higher rank members (old members) merit points based on their rank is to help to grow this community, because higher rank members surely know which one is a good post and which is not. Higher rank members have a lot of smerit points that can be given to other who needs, so you guys may contribute too to measure which person deserves a higher position, and there is no use to hold your smerit points as it may decay.
Being a high-rank member doesn't necessarily mean having a good judgment on how good/bad a post is.
There's a lot of Sr. Member and even Hero Member who still do a shitposting on this forum and it doesn't quite reflect their position as a high-rank member.
