auto invite facebook group

anyone can share in here working script auto invite facebook group ???

You can find a simple extension for Chrome named Facebook Groups Invite All. It works pretty good, but be careful to close the script at <500 friends invited because it's possible that Facebook will ban this function to your account for two weeks. I think that after some hour you can continue to invite the other friends, but I'm not sure about that.
Good luck!

I think no one will share it for free..
