Internet Blog

I wrote a guest blog on a popular blogsite a few years ago, and since then,
many people have emailed me in response to it. There were no official
requirements in writing the blog. I simply emailed it, and it was posted. I
no longer want my name or likeness to be associated with that blog entry. I
want it removed altogether or submitted anonymously.

You unfortunately don't have that right under most blogs.

You can try to tell them that you understood
you had a right to remove it--but that is not the way it works generally.

That's the beauty and the danger of the blog--once there it never goes away unless the site removes the page for some reason.
