Rumour 2: A new type of buddy list! Just send a group message to 10 or more users!
"Right click on your group name of your buddy list and check send this message to all the people in this group Copy this and send it to your friends in the group. If you send this msg to 10 people, a new type of buddy list will appear! It will tell you where someone is, who they are talking to, and if they have more than one screen name."
Achieved: This is false, there is no such thing, even though the person sending you the message probably precedes the text with a statement such as "it actually works!". Again like the above, the user just hopes that the message somehow floods Yahoo! servers, and enjoys watching people unknowingly contribute more messages into the Yahoo! system. It's also possible under some conditions, sending such large amounts of messages could cause a temporary block on your account.
Danger: In extreme circumstances, a temporary account lock.
