As for the posters on the Internet, or mass mailers, or so-called "50-cent party", or pushers, such as land agents, link retailers, and online day laborers... these new terms that frequently appear on the Internet have become real new professions. The IT forum operated by Linker has a relatively high PR value, and both Baidu and Google have high收录 (inclusion rates). Perhaps because of this reason, the posts by online marketers come in all shapes and sizes, making their various ugly behaviors simply jaw-dropping.
