Is it possible to keep people from "following" you? I just signed up for twitter and within the past 2 days I've had 5 people I've never heard of "following" me and that just makes me uneasy.
Go to your list of followers and click "block" which is right next to the button to follow that person.
I do it all the time.
OR you can go to your personal settings and set it to private so that only people that you approve can see your updates.
