There are a lot of Follower engines on Twitter that will mention you can sign up 100's of new connections with other people if you list with them, and as you'll find out, their listing requires giving them your Twitter password, which they promise not to share with anyone.
What they are not telling you, is they will use their own site under your name to spam everyone on your list, as if the Tweets/postings are from you, and not from them. So, if you see a get more Followers engine there and it requires your password, don't give your password up. I did, and then I changed it to something else. I have seen listings from Hypnotists here as if they sent those Tweets out, they didn't, and didn't know.
