Of many posts in WO deserve merits. And many users there doesn't even have a signature campaign..
Yeah so they don't need merits... not to re-open this can of worms but its long been a hive for merit farming suckups, who IMHO detract from the overall vibe of the WO.
The problem (if there is such a thing) is that some Newbies use it to earn (or "farm") Merit, but that only works because some other users think their posts are worth it.
These "other users" you speak of... a couple of them perpetuate the cycle and so the farmers return, like a festering plague. To be fair, sometimes people (myself included) don't even realize they are meriting an account farming weasel (and you probably don't even like their other accounts) until its too late.
