There are five main Korean fansites: DNBN, Yuerubi (유애루비), Ikadong (이카동), DC TVXQ gall, Telzone.
Before I explain the differences between these fansites, let me make one point clear first.
Cassiopeia, as used in fandom vernacular, stands for all fans that support TVXQ.
(Although to be an official Cassie, you must join the fanclub which is operated by SM.)
Therefore Cassiopeia includes all fansites that are in existence.
Now let me address the differences between fansites.
1. DNBN
DNBN is one of the most representative Korean fansites. Until recently, they supported all five members.
However, they changed their stance since 2-member TVXQ’s comeback. To read their current stance, please visit www.dnbn.pe.kr. *
2. Yuerubi (유애루비)
Yuerubi is the biggest fansite, having nearly 750,000 members.
Among major Korean fansites, Yuerubi is the only site that still supports all five members.
The age of the members are rather young compared to other sites. Yuaerubi’s daily traffic has gone down significantly in recent years so its large membership is deceiving of actual fandom climate.
