it most likely has to do with you doing steam market automations, which without generalising too much is typically what most chinese steam accounts getting account lockdown for is about.
Without judging, i think that would make sense when i look at your csgo inventory, is probably what you got caught doing.
EDIT: but i also doesn't really matter what i think you might have done, as nobody but steam support and yourself really knows what you have been doing and only steam support can really help if you believe you done nothing wrong.

这很可能与你做蒸汽市场自动化有关，在不太概括的情况下，这通常是大多数中国蒸汽账户被锁定的原因。 没有判断，我认为这将是有意义的，当我看你的CSGO库存，可能是你被抓住做的。 编辑：但我也不在乎我认为你可能做了什么，因为除了蒸汽支持和你自己真的知道你一直在做什么，只有蒸汽支持才能真正帮助你，如果你相信你没有做错。

说错了，是有意义的。
