No. The term "Zoner" is only used to describe a loosely affilitated group of individuals who, under certain circumstances, occasionally unite for a cause. The exceptions to this is, of course, official Zoner factions which consist of permanently allied groups of people used to be free roaming Zoners.
Technically, people in official Zoner factions shouldn't be called Zoners but they have to have some sort of faction identity.
People who treat Zoners as a faction like any other are obviously ignorant.
