透過 DMCA takedown notice 非法下掉 Easylist 內的過濾條件

參考「Ad blocking is under attack」這邊,有業主 functionalclam.com 透過 DMCA takedown notice 發信要求 Easylist 移除過濾條件 (參考「2017-08-02-LevenLabs.md」),對應的 commit 參考「M: Removed due to DMCA takedown request」) 這邊。 這件事情再次證實了 DMCA takedown notice 被濫用的情況,明明不是侵權的情況卻被拿來濫用 (因為對原提出者唯一的處罰必須過反過來提告,然後要得自己舉證因為這樣受損)。 目前看起來 EFF 願意介入,就來看看後續了。

用 Google 的 Speech Recognition API 破 Google 的 reCAPTCHA

就是「以子之矛,攻子之盾」的概念,用 Speech Recognition API 破 reCAPTCHA:「ReBreakCaptcha: Breaking Google’s ReCaptcha v2 using.. Google」。 就算 Google 在 reCAPTCHA 的聲音裡面加入 watermark,讓自家的 Speech Recognition API 拒絕分析,還是有其他家的可以用 (像是 Amazon Lex 或是 Bing Speech API),所以這樣做不是什麼好解法。

uBlock Origin 支援的 :has()

查資料的時候發現 uBlock Origin 的「Static filter syntax」已經自己實作 :has() 了 (雖然有一些限制)。 這個 CSS4 (draft) 的特性目前還沒有瀏覽器支援,所以 uBlock Origin 決定自己來: This is a planned CSS4 operator, but no browser supports it yet. I decided to go ahead and implement it so that it can … Continue reading
