@Bold Which I believe led to being more creative, all in attempt to power up their rep bar.
Well there's only a handful of FGers, many of the other members get their high post count from RP. At least, that's what I have seen RPers say. "Your post count can increase fast when RPing."
EDIT- Just to elaborate a little more, I've been in two RP villages. I know about the taverns and such, a lot of spam goes on in there. Then there's the RP as a whole, which includes Konoha Town, this place is the METROPOLITAN of spam. It also consist of creating an imaginary character and having them talk to another, which is essentially what the Ninja World is. I don't know who judges the value of these posts, but the RP seems to be important for a lot of people. Obviously as adults, if we were to debate what is more valuable; creating imaginary characters and having them fight each other (sometimes bickering and complaining whenever rules are added, stuff taken away, changes suggested etc.), or participating in very simple games with friends (which has its own share of complaining as well), the premise itself would make the argument redundant outright silly. Not to mention, it would be one big battle of hypocrisy. However, I think that many of the members with high post counts are from the RP world. The others are of course from FG, but there's only like 15 of them (compared to the massive world that is RP), and probably like 3-5 dedicated ones (some of them are even RPers).
