Easter Egg

Another non-friend attack. Easter Egg lets you post messages on your profile that only certain friends can read. Like other apps, you can trick it into leaving messages for people who aren't your friends. Because it's on your profile there isn't much danger here, but the app will give you the option of sending a notice to the recipient. They might not appreciate receiving messages from people they haven't added as friends, but that's about as much damage as you can do with this bug.
