为什么抓取频次突然减少？

抓取频次突然减少可能是由以下原因造成的： 1. 网站更新或改版：当网站进行更新或改版时，可能会暂停服务或改变页面结构，导致爬虫无法访问或抓取数据。 2. IP被封禁：如果爬虫使用同一个IP地址多次访问某个网站，网站可能会将该IP地址封禁，导致无法访问或抓取数据。 3. 爬虫程序出现问题：如果爬虫程序出现错误或崩溃，可能会导致无法正常抓取数据。 4. 网络连接问题：当网络连接不稳定或遭受干扰时，可能会导致无法访问或抓取数据。 5. 数据库容量不足：当爬虫抓取的数据量不断增加，可能会导致数据库容量不足，无法继续存储数据，从而导致抓取频次减少。因此，需要仔细分析和排查以上原因，并采取相应的措施来解决问题。

压力反馈工具更名加临时闭站功能

我们将压力反馈工具更名为"Stress Relief Tool"（压力减轻工具）以更准确地传达其功能。此外，我们还加入了临时闭站功能，以满足用户对临时休息的需求。当用户感到过度压力或疲劳时，他们可以选择暂时关闭工具，并自动弹出一段放松和休息的建议视频或音频。这个功能可以帮助用户更好地管理他们的压力，并提供他们需要的休息时间，以迎接新的挑战。
