building many accounts

I made another thread about this but didn't really get the answer I was looking for.
So i'm trying to set it up for 10 twitter accounts (girls) to be on complete auto pilot, and the real goal is to try to set them to tweet on they're own every couple hours, and to have the tweets actually look real and not spammy

Someone had mentioned something about grabinbox, but I have no idea anything about that program.

Google grabinbox and get ideas and tutorial on YouTube.
You will learn

...waiting for the igers spammy guys....

I was thinking to suggest you FL, but they have some problems with the tweets right now I suggest you to wait some time
