Internet activist Wen Yunchao on Sunday launched a cyber manhunt on Twitter aimed at five experts and technical personnel who helped improve China's Great Firewall. Wen encouraged Net users to find out whether the five, four of whom are professors and postgraduate students from a university in Nanjing, have any personal issues or are engaged in academic corruption.

Wen is a radical political dissident, who was disciplined many times at his Chinese university for various reasons. After he began his studies in the US in 2009, he gradually became a democracy activist against the Chinese political system.

Wen often voices aggressive opinions over freedom of speech and judicial justice. But the manhunt he initiated is a far cry from his philosophy.

These cyber manhunts go severely against cyber ethics, and for a number of reasons are violations of the law. However, it is unfortunate that Twitter has done nothing about it after the case was reported by some Western media. Imagine if Edward Snowden called for a cyber manhunt against all the designers of the US surveillance program PRISM on social networks, would Twitter still be so indifferent?

Certain dissidents have totally lost their moral bottom line nowadays. They flatter themselves that they stand on the moral high ground. Assuming that they did everything for a just cause, they think they can thus trample on ordinary people's codes of conduct.

Every country is responsible for its own cyber management. Technical inventions by a few researchers do not have any political nature.

Yet Wen attacked those technical workers online because of objections to the Chinese firewall. Such paranoia is familiar to us.

No matter how many grudges one has over social governance, he cannot publicly infringe on the rights of others like Wen has done. Otherwise, the entire society will fall into chaos.

After some dissidents fled to the US and other Western countries, they have not only had "more freedom" to express their political views, but also showed the dark side in their humanity. They seem to be so anxious to witness great disorder in China in no time. There is no telling whether their behavior stems from their own issues or the influence of the anti-China forces in the US.

That these malcontented dissidents living abroad, who are losers in life, are washed out by China's reform and opening-up is amusing and thought-provoking.
