幹壞事是進步最大的原動力
Verizon 一直在把 Yahoo! 手上比較有價值的資產賣掉，總算是輪到 Tumblr 了，這次是賣給了 Automattic，也就是 WordPress.com 營運的公司。
Verizon 已經發新聞稿了：「Verizon Media announces sale of Tumblr to Automattic」，Tumblr 的 staff blog 上也發表了：「Hello Tumblr ? Today, Tumblr’s owner, Verizon...」，但 Automattic 這邊還沒看到：「Features, news, and more: See what’s been going on in Automattic’s world.」。
金額不確定多少，但感覺應該算是好事？不知道之前的 porn content 會不會回流...
Facebook 新的防範報復性照片計畫不少媒體都有報導了，我拿 Bruce Schneier 這篇來引用好了：「Facebook Fingerprinting Photos to Prevent Revenge Porn」。
重點是：
According to a Facebook spokesperson, Facebook workers will have to review full, uncensored versions of nude images first, volunteered by the user, to determine if malicious posts by other users qualify as revenge porn.
智障... 結果裸照從這些管道先傳出去？
Bruce Schneier 提到了最近幾個剛好相關的議題，關於機器學習在情色產業使用時遇到的隱私議題：「Technology to Out Sex Workers」。
第一個提到的是 PornHub 用機器學習辨識演員以及各種「其他資訊」，這邊引用的報導是 TechCrunch 的「PornHub uses computer vision to ID actors, acts in its videos」：
PornHub is using machine learning algorithms to identify actors in different videos, so as to better index them.
The computer vision system can identify specific actors in scenes and even identifies various positions and… attributes.
第二個提到的是花名與真實身份連在一起的問題：
People are worried that it can really identify them, by linking their stage names to their real names.
最後是提到 Facebook 已經有能力這樣做，而且已經發生了：
Facebook somehow managed to link a sex worker's clients under her fake name to her real profile.
Her sex-work identity is not on the social network at all; for it, she uses a different email address, a different phone number, and a different name. Yet earlier this year, looking at Facebook’s “People You May Know” recommendations, Leila (a name I’m using using in place of either of the names she uses) was shocked to see some of her regular sex-work clients.
這個議題與 Mass surveillance 有點像...。
