does newbie need merits to rank up !? I don't think so, if I'm not wrong.
Why do they buy merits ? I guess they don't read the rules properly. and
who would sell merits ? Legends ? Hero ? Senior ? I don't understand if they would like to sell merits for some bugs. they have been here that long and still needs some bugs ? if they does, what have they done in that long time in this forum ?

I'm not fool enough to suspect those old members would sell Merits, I suspect multiple accounts do this.
Let's be positive, no need to be panic, coz all will be fine..
