Yeah, so you get more medals from realmmates. That's who you know, and who knows you. Again, the only "bonus" would be a high listing on the join realm pages. Which helps lure people to your realm.
If people are trying to "game" the system for the sole purpose of getting more people to join the realm, that would make me think they'd put some effort into retaining those people.
And...This is...A bad thing?
