【新唐人2013年03月09日讯】中国最大的微博营运商《新浪》微博,目前已达5亿用户,每天发出上亿条贴子。最近,美国媒体揭露新浪“删帖”的内幕说:30%的帖子在发出5-30分钟内就被删除。为什么新浪微博删帖”如此神速?谁在控制这个大机器﹖请看以下这则报导。

美国德州休斯顿市的“莱斯大学”计算机系教授沃勒克,和他的同事们,在《新浪》微博收集了数百万帖子,并进一步分析和识别审查员的规模和删贴速度。他们把研究成果,发表在“麻省理工学院”的《MIT技术评论》杂志上。

研究人员把目光锁定在3,500多名曾经遭到删帖的用户账号上,从去年7月20号到9月8号,对这些账号进行了15天的跟踪观察。他们发现,这些用户每天约有4,500个帖子被删,占总发帖量的12%﹔其中,“5%的删帖”在微博发出后8分钟内完成,“30%的删帖”在30分钟内完成,“90%的删帖”在24小时内完成。

被删除的微博会显示“此微博不适宜对外公开”,而被用户自行删除的则显示“该帖不存在”。有些贴子在发出的5-10分钟内被删,这表示微博管理员的审查时间“几乎是实时进行”。

网友“秀才江湖”指出,删贴不成,还可以封微博账号,或者直接删除账号。网友“秀才江湖”:“我的号经常被封,在开两会了,十八大了,就怕我说了什么不爱听的话,就把我的号封了。不让人家在网上说,人家就到街上去表达。今天‘满屏尽是转世党’,明天就会‘满城尽带黄金甲’。不让人说,就用行动来表达。”

中国独立记者、自由作家昝爱宗也多次被《新浪》删号。他指出,《新浪》删除用户的账号,从来都不通知一声,直接删除,而且还多次删,目地就是不让人说话。

中国独立记者、自由作家昝爱宗:“新浪非常无耻,国家在做它的后台,所以它才肆无忌惮,如果没有这个国家后台,它早就关掉了,或者是它要接受处罚,比如说,封号,你封用户的号,用户要求你赔偿,一个用户要求赔偿一、两万的损失,如果有一亿用户来要求它赔偿,那不得把新浪赔死。”

据报导,北京建立了“党组织”的重点网站共9家:《百度》、《新浪》及《第一视频》等都成立了“党委”,北京地区26家主要网站中,《百度》和《新浪》是互联网企业中“党组织”建设的先行者。

北京维权人士李金成指出,《新浪》在各地都设有党支部,网络删贴早被中共当局做为政治任务来抓了。

北京维权人士李金成:“只要是你力挺政府的,可以保留,但是你对政府批评的,或者是你披露外界不怎么知道的消息,所谓的敏感信息,它马上删掉,它们对重点人员进行监控。”

《新浪》微博用户众多,平均每分钟有7万个新帖子。研究人员估算,《新浪》一个审查员如果每分钟阅读50个帖子,那么扫描每分钟涌入的7万帖子,需要有1400人同时工作,假设他们每天工作8小时,就需要有4200人才能满足审查需要。

那么《新浪》是如何做到迅速发现并删除敏感帖子?

研究人员推测,微博的审查系统,通过运用人手和软件监控,套用能启动不同审查程序的多个封锁关键词列表,搜索过滤系统等,变成一个极度复杂的系统进行删贴。

而昝爱宗指出,《新浪》是个庞大的公司,各地都有办事处,公司招聘的管理人员不少于3万名。光微博这块,就有一个庞大的队伍来监控管理,现在维稳是中共政权的第一任务,所以当局就不择手段的来删贴、封号。

Sina Weibo Rapidly Deleting Microblogs

Sina Weibo, China’s largest microblogging
operator, currently has 500 million users.
It issues hundreds of millions of daily postings.

Recently, U.S. media exposed the inside
story of rapid deletion of Sina Weibo postings.
It reported that 30% of posts would
be deleted within 5-30 minutes.
How can Sina delete posts so rapidly?
Who is in control of this big machine?

Dan Wallach, Professor of Computer Science
at Rice University, along with colleagues,
collected millions of posts from Sina.

After further analysis and identification of
deletion and posting, they published their
results in the MIT Technology Review

The research focused on 3,500 user accounts, with
posts deleted between July 20 to September 8, 2012.
15 days of tracking observation
showed 4,500 posts were deleted.
That accounts for 12% of the total postings.

5% were deleted within 8 minutes of posting, 30%
within 30 minutes, and 90% were within 24 hours.

After deletion, the website showed the
warning, “microblog unfit for public viewing.”
When posts were deleted by users themselves,
the website would show “post does not exist.”
Some posts were deleted within 5-10 minutes,
showing the censorship is almost simultaneous.

One web user pointed out that if deletion fails,
they can also close or delete your account:
“My number was often blocked during
the two sessions, or the 18th Congress.
They were afraid that I said something
unpleasant, so they closed my account.
If they forbid others to express themselves
online, people can go on to the streets to talk.
When freedom of speech has been taken away,
people can express themselves in actions.”

Zan Aizong, an independent reporter and freelance writer,

whose account has been deleted often by Sina, says
that Sina deletes users’ account, without informing them.
Sina does it directly, and often
repeatedly to stop you from talking.

Zan Aizong: “Sina is very shameless. The
regime is supporting it, so it can be very blatant.
Without the backing of the regime, it would
have been shut down or paid a severe penalty.
For example, if you close users’
accounts, they will ask for compensation.
If everyone asks for 10-20,000
yuan, Sina will be broke soon.”

It is reported that Beijing has established
nine “party organization” focus websites.
“Baidu", “Sina" and “First Video"
all have party committees.
Among the 26 websites in the Beijing region, Baidu and
Sina Weibo are pioneers for “setting up party organizations.”

Beijing human rights activist Li Jincheng points out
that “Sina" has party branches all over the country.
Deletion of postings is a political
task for the Party officials.

Li Jincheng: “As long as you are behind the
government, you can keep your postings.
If you criticize the government, or disclose
something to the outside world, the so-called
‘sensitive information’, it is immediately deleted.

They are monitoring key personalities.”

Sina Weibo has many users, and an
average of 70,000 new posts every minute.
Researchers estimate that a Sina censorship
inspector reads 50 blogs per minute.
It would need 1400 people to scan 70,000 posts.

If staff work 8 hours per day, a total of 4200
people would be required to meet reviewing needs.

How does Sina delete sensitive postings so quickly?

Researchers speculate that it is
being done by a review system.
Using manpower and software, lists of keywords, and
search filter systems, a complex deletion system is created.

Zan Aizong points out that Sina is a huge
company, with branch offices everywhere.
It recruits more than 30,000 managers, and there
is a large team for monitoring microblogs alone.
When maintaining stability is the regime’s first task,
authorities will be unscrupulous with deletion of postings.
