I'm not sure if this is a feature or a bug...but with the way new Facebook groups work, you can add anyone on your friends list to the group, and they instantly become members of the group, without them having to confirm their membership or do anything.
This may mean they get notifications from the group without actually agreeing to anything.
I made a sample group to try this out:
Login | Facebook
Let's see how many people we can add to this group without their consent.
