This plugin helps creating more privacy for blog comments. It hides the input fields for e-mail and URL in new blog comments and omits storing the IP addresses of commenter in the WordPress database. It also disables the notice that e-mail addresses are not being made public. This helps to reduce the data collected from users and as such can be part of a good privacy approach for your blog. Please do read the FAQ section for important further details.
