Main contributors of GFW should be denied entry to the USA

In China, Great evidences show there are a few people who are using their knowledge for blocking others to use the Internet for a certain groups. Thousands of websites, including Facebook and Twitter, have been blocked. A government organization, China's National Network and Information Security Administration Center (NISAC, also known as CNCERT/CC), has been actively building the Great FireWall (GFW) over ISPs' network for filtering the packets and monitoring the communications. We petition the Obama Administration to boycott such behavior, and deny their visa applications and immigration requests.
Here is a list of the main contributors of GFW which are retrieved from the article - GFW's Past and Present - which is widely admitted.
