The main reason for this is maybe is that there are too much dupers in game... have you noticed bunch of white gems in 10 sets being sold by 1 person?? OMG...
dont believe me? check these out... these are pics are from server 1
Seriously, can a normal player without cheat earn that much stones? i have 4 level 55 chars in server 1 and i was only able to obtain 6-8 white gems for each account i have...

on the other hand here's a complete translation of the post by salza...
Hello dear players,

Normal service operation to ensure compliance implementation, server maintenance phase this week, will be shut down simultaneously the following functions:
§ Cash Mall "Adrian Lats warehouse key" button to lock the purchase and gifts
§ the world's largest market, selling button lock (i believe this is for the Auction House)
§ mail send button lock (obviously the mail function)
§ schools to apply to lift lockout feature
§ temple battle Lock
§ the role of the Delete button lock
