Most services and newsletters let you simply click on "unsubscribe" and then you're done. This is my favorite type. Some make you send them a blank e-mail or login to "change your preferences". This request bugs me.
Very rarely do I get the "Please confirm by typing the word in the box below." request to unsubscribe. But I understand why companies ask for this, and I have no problem doing so.
When unsubscribing, I love it when companies write "We're sad to see you go!" or "Sniff Sniff please don't leave us." It gives a more personal feel, and once or twice I've actually reconsidered. But I'm not sure what this particular company was trying to tell me with the "random" word they chose for me to type in...
