Is this another Urban Myth?

FW: Message from Mr Allen Smith (Manager of Friendster):

" Friendster system is getting too crowded!! We need you to forward this to at least 20 people. I know this seems like a large number, but we need to find out who is using their account. If you do not send this to at least 20 Friendster members, we will delete your account.

WARNING! We want to find out which users are actually using their friendster accounts. So if you are using your account, please pass this e-mail to every Friendster user that you can. IF YOU DO NOT PASS this letter to anyone we will delete your account. Sorry for the inconvenience."
