The Zimbabwean government has proposed obliging its internet service providers to divulge details of e-mails deemed offensive or dangerous. Zispa, the local ISP association, has asked the government to clarify its proposed addendum to providers' franchise contracts. One ISP told BBC News Online it was not a provider's duty to police the net. President Robert Mugabe has suggested the internet, widely developed in Zimbabwe, is a tool of colonialists.
