Can you get banned for trading Genshin?

Excuse me, could you possibly clarify for me something regarding trading Genshin? I've heard rumors that individuals have been banned for engaging in such transactions. Is this truly the case? Are there specific guidelines or policies in place that outline when and why one might face such consequences? And if so, are there any ways to avoid inadvertently falling into such a predicament? I'm quite interested in understanding the potential risks and safeguards involved in trading Genshin.
