（一）"数据库依赖症"引发误判连锁反应 当前国内外AI检测系统主要依赖公开资料库及联网搜索比对机制，而经典文学作品因其广泛传播和高度引用，极易被判定为"与现有内容高度重合"。例 如，朱自清的《荷塘月色》因长期收录于教材、文献，其片段被系统标记为"高度疑似AI生成"（AI率62.88%）。 当"AI率"检测系统从"学术辅助者"异化为"新型学术税"的征收者，当"反AI文本"成为一门暴利生意，学术诚信的底线正被技术漏洞与人性贪婪 共同撕裂。在这场荒诞的猫鼠游戏中，学生、商家、平台三方围绕"AI率"展开一场"技术对抗技术"的黑色狂欢，而学术尊严与教育的本质，早 已沦为这场闹剧的"牺牲品"。 当前，毕业论文季的硝烟弥漫全国高校。 复旦大学、西南大学、中国传媒大学等十余所高校相继出台新规，将"AI生成内容检测率"（AI率）纳入论文评审硬性指标，要求本科论文AI率不得超过 15%、硕士论文不超过10%、博士论文需低于5%。这场以"技术监管"为名的学术变革，却在执行中演变为一场"人机对决"： 学生被迫与AI"斗智斗勇"，用方言插入、错别字掩护、甚至手写扫描再转录等"土办法"降低AI率；教师沦为"算法的执行者"，在"降AI率" ...

Group 1 - The core issue revolves around the reliability of AI detection systems, as classic literary works like Zhu Ziqing's "Lotus Pond Moonlight" and Liu Cixin's "The Three-Body Problem" are flagged with high AI generation probabilities, raising doubts among netizens about the accuracy of these tools [1][2] - A practical test conducted by reporters showed that the AI generation probability for "Back Shadow" was 18.21%, while "Ball Lightning" had a probability of 32.05%. Other AI detection websites reported even lower rates for "Back Shadow," with some showing less than 1% [2][4] - AI detection models are based on training with large datasets of both human and AI-generated texts, but they can misjudge due to the evolving nature of AI-generated content. Continuous updates to detection models are necessary to reduce misjudgment rates [4][6] Group 2 - The discussion on social media regarding the high AI detection rates in academic papers suggests that educators should not rely solely on these results as a measure of student performance, but rather consider them as part of a broader evaluation system [6]
