I know the accounts you're talking about.
They all post quotes, funny tweets, inspirational tweets. And all the accounts seemed to be linked, after a while they'll tweet one another and RT saying follow this account, then they'll get the favor in return and those tweets will eventually be deleted.
I still am unsure in what you're asking though.
I don't know how to get into the circle of that group but i sure want to be. I'm doing it solo though. Just following a bunch of people hoping to get followers in return.
