"SELECT ALL FRIENDS" code is working or not ?

Hello,

I am still using the code to select all the friends and invite on groups or fan page, and it select most of the friends, someone won't be selected because they are already in the page or refused in the past, and that's ok, but all the selected invite will be sent out or no?

Anyone can confirm?

Thanks!

It's still work with me when i try to select all of my facebook friend to suggest become a fan of fanpage.
