Hi Everyone

This is my first post here, so be gentle
I'd like to know what is the best software to use to spam facebook and users to join a group ( so , beeing the group owned, i could continously advertise products to group members ).
I've tried to use Facebook Friend Bomber and facebook deleted my account..
Is there a program that creates multiple accounts and sends invites from them ?
I've used the search option here but couldn't find anything.

Thanks a lot in advance
