why are newbie posts always considered spam?
Because of bullshit posts like this one you made, a question that's been answered many times since January:
is it possible for me to get merit
And this one made by someone else, which makes no sense to me what he's trying to say:
post rule I think that is important to keep forum clearly with useful staff, but the merit requires are so high, a little people could do it for others.
The problem is that the main section on bitcointalk is in English, and many noobs who came here because they heard their neighbors/family/coworkers/pagpag eaters living on the street/whoever were making big money just by posting. Then they come here and find out that not only do they have nothing to say about bitcoin, but they can't even express basic thoughts coherently in English--and that other, more well-established members don't appreciate this, because it makes the forum unreadable, literally.
The merit system was designed to combat the above situation. Hell yes it's hard for non-English speakers to earn merits unless they do so on the local boards OR if they make valued contributions to the community in the form of scam-busting or the like. I've seen a few members rank up based on how helpful they are and not because their English is excellent.
