LinkedIn seems to be an all-around stubborn and inconvenient site. I had the same experience, but in my case it was in deleting my account. The deletion process was unnecessarily difficult, so I deleted all my contacts (I think the account ultimately did get deleted though). The reason I wanted to delete my account in the first place had to do with the fact that it was overly restrictive in managing, showing, deleting my own content. The last straw was that I had posted a question in the public Q/A section and there was no way to delete the question permanently when I did not want it to be shown.
