Basically I have been confided with a certain amount of twitter accounts to do maintenance work or edit the design for my colleagues. I was wondering if I could use it to my advantage as some have up to 4k followers. Obviously I can't just post a tweet asking their followers to follow my account as they'd realize it but I was thinking maybe a Welcome DM to their new followers perhaps? What free services would I use (where I dont have to sign up each account individually)? Also just curious, for myspace there use to be friend exchange train sites like InfiniteAdds . How come I haven't seen any proper ones for twitter? is there a problem with those who follow only to get points and then unfollow?
