I stupidly joined something called 'the twitter train; Now it keeps sending automatically tweeting to my account about how many followers the train has got me, and I can't stop it. I can't login I sent them a email - not joy. And I only got 1 follower out of it! What a scam. Steer Clear!!!
Thanks for the info i will stay away.. But might be your account there would be hacked so you wont be able to log in..!!
go to settings > connections and revoke access to the application you want, you can change your pass as well, but the settings if how you actually remove the program I don't care for anything that auto post a message like that, I unfollow all those.
You gave them your password. Not a smart move. Change your password for a day or two and they will go away.
Most of the 'auto' twitter builders are pretty much dead; TW put the boot down big time on auto accounts and software lately.
