My four accounts have been disabled. Please check with GM management

GM Administrator:
Hello, I have four accounts. The character names of the accounts are dragonflying(shaman), tiger flying(rogue), bismark(hunter), and fireflying(warlock). On March 31, 2023, I found that all four accounts were blocked. I thought carefully about whether there were any violations in some of the things I did, and found that I had not done any violations. I only traded some mongoose and giant potions from my own shaman dragonflying to the rogue tigerflying and the hunter bismark. Besides, I may have traded dozens of gold to the rogue tigerflying. “I didn’t expect trading my own account number to be illegal, because I thought it was all my own account, so trading a little bit shouldn’t matter, but I suspect these are the reasons why my account was blocked.”. I hope to make an explanation here, so that the GM administrator can understand that these transactions are all under my own account, and there are no offline transactions. Please check with the GM administrator. If it is indeed a mistake, I hope the GM administrator can unban my accounts. Thank you very much!
中文:GM管理员:你好,我有四个账户,账户的角色名分别是dragonflying(萨满号)、tigerflying(盗贼号)、bismark(猎人号)、firflying(术士号)。在2023年3月31日这一天我发现这四个账户都被封禁了。我仔细回想了一下我做的一些事情是否有违规,发现我并没有做什么违规的事情。我只是用我自己的萨满号dragonflying交易给过盗贼号tigerflying和猎人号bismark一些猫鼬和巨人药剂等,另外还可能交易过几十G给盗贼号tigerflying。我也没想到交易给自己的号也可能违规,因为我想着都是我自己的账户嘛,交易一点点应该没关系,但是我怀疑这些就是导致我账户被封禁的原因。我希望在这里做个阐述,也能让GM管理员了解到这些交易都是我自己的号交易给我自己,并没有线下交易的情况。请GM管理员核实,如果确实是误封,希望GM管理员能给予解封,感激不尽!
