分析 FCC 對網路中立性的留言,將鄉民與機器人分開來分析

Boing Boing 的立場其實還蠻鮮明的,所以有時候他們的新聞看看就好...

但這篇真的很有趣,把 FCC (美國的聯邦通信委員會) 上兩千兩百萬則對網路中立性的留言拿出來分析,結果發現真人與機器人的差異超明顯 XDDD:「Analysis of 22 million FCC comments show that humans love Net Neutrality and bots really, really hate it」,引用的文章在「Discovering truth through lies on the internet - FCC comments analyzed」這邊。

分析可以發現,真人偏好網路中立,而機器人反對網路中立 XDDD:(其實大家心裡都有底是怎麼玩出來的... 只是這次有機會分析,讓事情更明顯)

Data analysis company Gravwell ingested 22,000,000 comments sent to the FCC's docket on Net Neutrality and posted their preliminary findings, which are that the majority of comments came from bots, and these bots oppose Net Neutrality; of the comments that appear to originate with humans, the vast majority favor Net Neutrality.

文章中列出幾個有趣的現象,像是機器人的 comment 大量重複:

A very small minority of comments are unique -- only 17.4% of the 22,152,276 total. The highest occurrence of a single comment was over 1 million.

甚至是 pornhub.com 的郵件位置 XDDD:

Most comments were submitted in bulk and many come in batches with obviously incorrect information -- over 1,000,000 comments in July claimed to have a pornhub.com email address

然後機器人的 pattern 也很容易辨別:

Bot herders can be observed launching the bots -- there are submissions from people living in the state of "{STATE}" that happen minutes before a large number of comment submissions

這個有點類似「50 Cent Party (五毛黨)」,但是是自動化機器人,而且產出的「品質」不太好 XDDD

Bitcoin 有單一團體超過 50% 計算能力了...

Bitcoin 的安全性是利用「當整個社群夠大時,不會有單一團體擁有超過 50% 的計算能力」的假設上發展演算法及防護機制:(參考「Weaknesses - Bitcoin」)

An attacker that controls more than 50% of the network's computing power can, for the time that he is in control, exclude and modify the ordering of transactions. This allows him to:

  • Reverse transactions that he sends while he's in control. This has the potential to double-spend transactions that previously had already been seen in the block chain.
  • Prevent some or all transactions from gaining any confirmations
  • Prevent some or all other miners from mining any valid blocks

不過讓人噴飯的消息出來了,即使在 Bitcoin 這麼火熱的情況下,仍然有單一團體計算能力已經超過 50%:「Largest Bitcoin Mining Pool Pledges Not To Execute '51% Attack'」。

這應該是當設計時始料未及的... XD
