If you don't do any logging and don't want to know what your users are doing - it means that you won't have to deal with the cops as much. And there won't be any risk of those logs getting leaked or stolen .
Unless you're de-facto part of the government like Google and Microsoft - I see no good reason to log anything more than what's legally required.
