[Hunters] never has been a clan that tried to recruit people. Instead, it was more like a family, as in, a group of people who just enjoyed playing the game for fun.
Now, if you invite a lot of new people just for the sake of keeping a clan alive, it's a rather alienating change of the clan, since it's going to lose this family-like basis. And that'd mean that the clan stops being the clan it used to be.
