Hi
I really need the list of AUTO FOLLOW BACK Twitter accounts. I found two list here with 18k per list but none of them working, I follow the accounts but they didn't follow me back.

Or please tell me how to get the AUTO FOLLOW BACK Twitter list.

Thanks for your help

why don't you just search active users who has words "follow back" in their description?
