Allowed is the wrong word.. we discourage it.
Even if they pretend they aren’t the author, we really base it on the source (Wordpress, Blogspot, etc) or content. Some are harder to catch or distinguish, such as Examiner which is mostly just bloggers but it has an appearance of a higher standard than most blogs, or TownHall which is more cream of the crop bloggers that could be considered news by most sources. That’s why we discourage it but sometimes they are in news for a reason.
I need an aspirin after thinking about all that.
OK, thanks for answering me.
