Baidu Space Junk Station

When Baidu Space first opened for registration, I once thought that this was the best personal space on Chinese cyberspace because of its simplicity. Although at the time, many people considered it to be too simplistic. But now, my Baidu account has been categorized by me as "zombie," lumped together with Sina Weibo and Sohu in the same group. My accounts on these sites are merely used for posting some junk information or creating link arrays. The most serious writing I do there is just ghostwriting promotional articles. Many times, I have doubts about my own behavior. Since I registered these accounts, I should take them seriously, but why do I classify them as "zombies"? Is it really because they were "easy to come by"?
