Currently on the server there are many clone accounts

I have 1 comments to the following quantity:
1. Those accounts are used to earn jewelry, most of those accounts are only Class 2 characters, why doesn't the admin limit the drop rate of gems for Class 2 characters? Only Class 3 characters have higher gem drop rate

2. The problem of fixed clone accounts to earn Class 3 quest items.. the administrator should ban trading those items, for those who are enthusiastic about the game, want to experience or can go to shop X with DvPoint
