r'''查 Gitee 到底为什么判违规，以及 README 里哪些词可能触发。

== 已知 ==

    https://gitee.com/xmz7891/ykxmz/raw/main/README.md  -> HTTP 451
    Unavailable For Legal Reasons

451 是"应法律要求不可用"。在国内平台上，这个通常是**内容审核拦的**。

== 要分清两种情况 ==

    A. 整个仓库被限制（那 API 读仓库信息也会失败/受限）
    B. 只有 README 这个文件被拦（网页能开、raw 不行）

== 同时扫一下 README 里可能触发审核的词 ==

国内平台的关键词审核对这几类比较敏感：

    * 翻墙 / 代理 / VPN / 科学上网
    * 挖矿 / 矿机 / 算力 / 虚拟货币
    * 破解 / 破解版 / 盗版 / 激活工具
    * 外挂 / 作弊
    * 监控 / 偷拍 / 窃听 / 追踪（"监控"在教育场景容易误判）
    * 游戏相关的"封号""加速器"
    * 二维码 / 收款 / 打赏

这份 README 是"教室手表控电脑"，正常。但要确认没混进上面这些。
