In recent years, there have been frequent cases of network neutral help behavior involving crimes. Neutral help behavior is permitted by the law,but it may actually promote the occurrence of crimes.It implies the contradiction between freedom of behavior and protection of legal interests. The net neutral help behavior is different from the traditional neutral help behavior due to changes in its accomplices,legal interest infringement, and meaning contact. Network neutral help behaviors are mostly carried out in the form of inaction. The author discussed the obligations and penalties of search service providers,cache and storage service providers, and network connection service providers respectively, in order to clarify the criminal standard of neutral help behavior, and finally realize the reasonable balance between the freedom of criminal law and the protection of legal interests.
