在 Hacker News Daily 上看到修改 booking.com 的 dark pattern 的套件：「De-Stressing Booking.com (alexcharlton.co)」，原文連結到「De-stressing Booking.com」，這是 2019 的文章，在介紹他寫的套件。
裡面講的是像這樣的東西：
這個例子裡面是故意用有壓力的顏色 (這邊是紅色) 去推動使用者趕快下單，算是蠻經典的 dark pattern，作者有舉個 Airbnb 的類似例子，比較起來就好很多：
在 comment 也有人提到其他種類的 dark pattern，故意把一些飯店標成已經售出，製造你不趕快訂就會釘不到的假象。不過下面有人提到，在有些法律制度比較完整的國家裡面，這會牽扯到不實宣傳之類的行為：
After browsing hotels for some time I've seen booking.com show several hotels start to sell out of rooms. That usually causes me to hurry up and book, but after several hotels showed full at once I got suspicious and checked my partners phone. The hotels still showed as available there. Dark stuff. Their website is otherwise pretty good though and I still use them.
在「Online hotel booking」這邊有英國對這些線上訂房網站的調查與裁罰。
然後在 Hacker News 上的 comment 有看到一個有趣的方法，是 PresidentObama 提到的方法 (這 id XDDD)，用 uBlock Origin 來擋：
From the last time booking.com was discussed I picked up some ublock origin filters that make the website more bearable.
You can copy and paste them directly in your ublock config (ublock options -> My filters)

另外還有擋一些追蹤的 url parameter：
Apart from these, I use some additional ublock filters to block some of their tracking that I am not ok with.

不過好像很少用 booking.com 了...
