Seriously, vonGenf? Can't we have a sincere discussion about this sort of thing without people just blatantly propagandizing in it?
On the forums, I think a certain amount of recruitment and propaganda is fine, especially within the individual continent subforums, and when people specifically ask for good places to play.
Within the game, though, I really don't feel like it's appropriate to send OOC messages attempting to induce people to join specific realms. If you want to recruit IC, and have your character say something like, "My brother in Fronen sends to say they're having a lot of trouble, and could use good warriors," while I don't think it's the best thing in the world to do, it's fully IC, and done for IC reasons.
This sort of OOC recruitment, especially just blatantly saying, "If you want to play an advy, create it in Fronen," full stop, is...I dunno, it just really rubs me the wrong way.
I don't think it's against any sort of rule, but it doesn't really feel to me like it's "playing a game as with friends".
