Is this behavior of GM a violation

I played with my friends. From level 1, I started to work together every day, upgrading, placing replicas, mailing each other, and trading with each other. Now that I have reached level 40, I only have enough to buy a pony. Can I trade with each other, G, and buy a horse?"

我两每天都组队一起玩,一起练级,1级开始,都是歪歪语音

建议不这么干,听说过这么干被封的而且是永久。

建议别这么干 太过危险 不值得

It’s best not to do this as there is a risk of account freeze
