对 Bilibili.com 的视频卡片元素，以标题、UP 主、标签、双重标签、充电专属、收藏投币比、竖屏、时长、播放量、点赞率、视频分区、UP 主等级、UP 主粉丝数、UP 主简介、精选评论、置顶评论来判断匹配，添加覆盖叠加层或隐藏视频，隐藏或屏蔽热搜、附带去除广告等非视频元素的功能。
< 脚本 Bilibili 按标签、标题、时长、UP主屏蔽视频 的反馈
太强了，没在b站泡个三年写不出这么多关键词。看这几个词就能想象视频封面了
额，抱歉，同时打开了多个脚本的页面，突然想写个评论就写了发出来，然后发现发错了也删不了，这是另一个脚本的屏蔽词表达式，可能在这个脚本用不了我没有试过，评价错脚本了抱歉。
世界因你而美好
那我也来分享一个, 快速获取视频标签的脚本.

非常好用，可以过滤掉很多垃圾视频，另外共享一下我这半年多写的一些屏蔽词的正则表达式，我自认为很有效的过滤掉很多广告、卖课等等的垃圾视频，其中关于编程、ai等等的割韭菜内容偏多，如果你要使用最好先筛选一下，避免误伤。使用方法：在
视频过滤->标题关键词过滤，填入正则表达式内。（表达式写法提示：以/开头和结尾，每行一个，其中用到两种屏蔽词，必须包含的词，和用|分割的任意词，没有用到复杂的写法，足够应付大多数场景了，也欢迎大佬共享一下更多有效屏蔽垃圾视频的表达式）
