Web 2.0 Summit: spam filtering between Google and Wikipedia

In Hollywood, if you are watched by paparazzi, it means you have succeeded. in Silicon Valley, if you are targeted by spam information, it means you have succeeded. On Wednesday morning, at the Web 2.0 Summit (Web 2.0 Summit), representatives from Google, Reddit, pramana, And Wikipedia talked about how to resist spam information.

Matt Cutts, head of Google's anti-spam team, said that if you provide link-related services, you will inevitably encounter spam information. Cutts talked about three types of spam, which are used by spammer to promote spam links to websites and submit spam content to webpages that allow user feedback; vulnerabilities found in some old CMS systems inject junk information into victim websites.

For spam information, we recommend that you use information filtering services such as akismet to deploy CAPTCHA, install patches frequently, and even pay for registration. He suggested that people jump out of their thinking circles and use unexpected methods to deal with spam information. If you make SPAM publishers feel frustrated, it is more effective than charging them.

Reddit
Founder Steve Huffman talked about some of the methods they used to mislead spam message senders. He said that Reddit is similar to Digg
Digg is a better service. Digg allows users to submit links to their favorite content and vote for published content. The higher the number of votes, the higher the chance of reading the content.

But Reddit is different. In Reddit, some votes are not counted. Once Reddit detects that someone is sending spam information, his account will be resisted,
Reddit will not notify the person who sends the spam information. His submission is still normal, but his submitted content will not be published. Huffman
It means we use some techniques to make spammers think their tricks are successful.

Jonathan hochman, the administrator of Wikipedia, talked about some strategies Wikipedia uses to respond to spam information and deliberate destruction. He said that we spent a lot of time keeping Wikipedia clean. In Wikipedia, 20% to 30% of editing operations are intentionally damaged and repaired.

Wikipedia is an online encyclopedia that allows anyone to participate in compilation, but it is rarely known that this site relies on automatic computer editing. hochman explains that some automated programs are involved in editing.

For example, cluebot participated in the editing of about 0.8 million articles. cluebot has done a lot of document restoration and repair work. If someone continuously destroys a page, it will notify people to intervene.

Sanjay Sehgal, CEO of praman, tells about their humanpresent technology, which is used to protect the Untitled massive number of player games they just released. He said CAPTCHA does not work, because it is easy to be cracked.

Pramana's technology will try to identify real users and automated programs. Too many robot players in a game will crash the game. This technology is not only used to block
Spam also helps improve user experience and provide traffic data. Since humanpresent technology was used, pramana found 12% to 15%
The traffic comes from robots.
