Fort Knox level account protection here

The number I heard was the hackers had info for 25,000 accounts in GMS. If I recall correctly Nexon reacently announced that it had 5 million users (this probably means accounts) and surely that was spread accross GMS, CMS, SEA, KMS, Europe, Bazril, etc... Does anyone know how many accounts (users) GMS claims to have?

I would imagine that GMS' population is much larger than KMS', so in that case on a new patch day (a new class) we probably have 270k+ concurrent users at least.

25,000 accounts is 10.8% of the GMS' user base.
