An interesting comment from a reader

Here is the censorship problem as I see it, for Google, Twitter, and all blogs that censor in some way:

IF you do not edit or restrict or act on posts, then you are a blind transmitter, like the telephone, the usmail, UPS, etc....

IF you decide to edit, restrict, select, censor, or in some way shape or form review, whether human or by human created software that follows human desires (or they would not use it), then you are a publisher and are fulfilling that role and ARE responsible for what is said that you did not remove.

Which is why blogs should not censor, they become publishers responsible for content.  Payment does not make a  publisher, being a gate keeper does
