Is there a way to automatically send a direct message to new followers on twitter

Let's all share the websites and techniques that we use to get free Twitter followers, Facebook likes, and Google +1s from.

Here are my top 3 websites that I use:

1) Tweers.com - Followers, Likes, +1s, Stumbles, YouTube Views
2) Twiends.com - Followers
3) TwitClub.com - Followers

What are yours?
